[0037] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0038] When cleaning carpets such as blankets and mats, debris such as particles and dust are located deep within the carpet. The cleaning components have difficulty sweeping the debris out from deep within the carpet, which affects the cleaning effect of the cleaning robot or cleaning equipment.

[0039] The cleaning apparatus according to an embodiment of the present disclosure is described below with reference to Figures 1-12.

[0040] The cleaning equipment in the embodiments of this disclosure is preferably, but not limited to, a sweeping robot and a sweeping and mopping robot.

[0041] As shown in Figures 1-12, the cleaning equipment of this embodiment includes a body 1, a patting component 2, a driving device 3, a transmission mechanism 4, and a detection device.

[0042] The body 1 contains a guide component 11, and the bottom of the body 1 contains a tapping and storing device 12. As shown in Figures 1-3, 7, and 10, the bottom of the body 1 contains a tapping and storing device 12 extending in the left-right direction shown in Figure 2, and the body 1 contains a guide component 11 extending in the vertical direction shown in Figure 2. As shown in Figures 1 and 7, in some embodiments, the tapping and storing device 12 includes a rectangular tapping opening. However, the tapping and storing device 12 of this application is not limited to a rectangular tapping opening.

[0043] The drive unit 3 is located inside the body 1. The drive unit 3 drives at least a portion of the striking component 2 to extend and retract from the striking and storing device 12 via the transmission mechanism 4. One of the striking component 2 and the transmission mechanism 4 is guided by the guide component 11. As shown in Figures 2, 3, and 8-10, the drive unit 3 is located inside the body 1, the transmission mechanism 4 connects the drive unit 3 and the striking component 2, and one of the striking component 2 and the transmission mechanism 4 is guided by the guide component 11.

[0044] When the drive unit 3 is running, the drive unit 3 drives at least a portion of the beating component 2 to extend (as shown in Figures 2 and 8) and retract (as shown in Figures 3 and 9) from the beating and collecting device 12 via the transmission mechanism 4, thereby beating surfaces such as carpets that are waiting to be cleaned, knocking out debris from the surfaces to be cleaned so that it can be cleaned and collected by the cleaning equipment.

[0045] The detection device is used to detect when the tapping component 2 retracts to its limit position. As shown in Figures 2-5, the detection device is preferably, but not limited to, located inside the body 1, and is used to detect when the tapping component 2 retracts to its limit position. In other words, the detection device sends a trigger signal when the tapping component 2 retracts to its limit position. In some embodiments, the trigger signal can be a light signal, an acoustic signal, or an electrical signal, preferably an electrical signal transmitted to the terminal of the cleaning equipment. When the cleaning equipment is cleaning a surface that does not require tapping by the tapping component 2, such as a floor or ground surface, and when the cleaning equipment is stopped or in standby mode, the trigger signal ensures that the tapping component 2 retracts to its limit position and remains there, to avoid collision damage caused by the tapping component 2 extending and to reduce energy consumption of the tapping component 2.

[0046] The cleaning device of this embodiment has a beating and collecting device at the bottom of the machine body. The driving device drives at least a part of the beating component to extend and retract from the beating and collecting device through the transmission mechanism. This allows the cleaning device to beat out debris from the surface to be cleaned, such as carpets, so that it can be collected by the cleaning device. The detection device is used to detect when the beating component retracts to its limit position, ensuring that the beating component retracts to its limit position and remains there when the cleaning device is not in operation or when the cleaning device is stopped and in standby mode. Therefore, the cleaning device of this embodiment has a good cleaning effect.

[0047] In some embodiments, the drive device 3 includes a drive shaft 31 and an eccentric shaft 32. The eccentric shaft 32 is connected to the drive shaft 31, and its central axis is eccentrically positioned relative to the central axis of the drive shaft 31. As shown in FIG6, the drive device 3 includes a drive shaft 31 and an eccentric shaft 32. The central axes of both the drive shaft 31 and the eccentric shaft 32 extend in the front-rear direction shown in FIG2. The central axis of the eccentric shaft 32 is eccentrically positioned relative to the central axis of the drive shaft 31. In other words, the central axis of the eccentric shaft 32 is parallel to and spaced apart from the central axis of the drive shaft 31. Furthermore, the central axis of the eccentric shaft 32 is parallel to but does not coincide with the central axis of the drive shaft 31. The drive shaft 31 drives the eccentric shaft 32 to rotate around its central axis.

[0048] The transmission mechanism 4 is pivotally connected to the eccentric shaft 32 and the striking component 2, respectively, so that the transmission mechanism 4 drives at least a portion of the striking component 2 to extend and retract from the striking and receiving device 12. As shown in Figures 2-6 and 8-12, the transmission mechanism 4 is pivotally connected to the eccentric shaft 32 in the front-back direction and to the striking component 2 in the front-back direction, one of which is guided by the guiding component 11.

[0049] When the drive device 3 is running, the drive shaft 31 drives the eccentric shaft 32 to rotate around the central axis of the drive shaft 31. The eccentric shaft 32 drives at least a part of the beating component 2 to extend out of the beating and collecting device 12 (as shown in Figures 2 and 8) and retract into the beating and collecting device 12 (as shown in Figures 3 and 9) through the transmission mechanism 4, thereby beating the surface to be cleaned, such as a carpet, and knocking out the debris in the surface to be cleaned so that it can be cleaned and collected by the cleaning equipment.

[0050] In some embodiments, the body 1 is provided with a main brush compartment 14, which contains a main brush for cleaning the surface to be cleaned. Along the moving direction of the body 1, the main brush compartment 14 is located behind the patting and storing device 12.

[0051] As shown in Figures 1 and 7, the main body 1 has a main brush compartment 14 extending in the left-right direction. The main brush compartment 14 has an opening on the bottom surface of the main body 1. The main brush compartment 14 contains a main brush that extends in the left-right direction and can pivot around the left-right direction. The main brush cleans the surface to be cleaned through the opening, for example, sweeping dirt from a carpet into the main brush compartment 14. The main body 1 can move forward on the surface to be cleaned. The main brush compartment 14 is located behind the tapping and collecting device 12 along the direction of movement of the main body 1. In other words, the main brush compartment 14 is located downstream of the tapping and collecting device 12.

[0052] When the cleaning equipment is cleaning carpets and other surfaces waiting to be cleaned, the machine body 1 moves forward on the surface to be cleaned. The surface to be cleaned is first beaten by the beating component 2 to knock out the debris in the surface to be cleaned. Then the main brush passes over the surface to be cleaned after being beaten and sweeps the original debris and the debris knocked out of the surface into the receiving cavity 11 through the opening.

[0053] It should be noted that the "surface to be cleaned" is not limited to the surface of carpets such as blankets and mats, but can also be the surface of the ground, floor, etc. In other words, the cleaning equipment of this disclosure embodiment is not limited to cleaning carpets such as blankets and mats, but can also clean the ground, floor, etc.

[0054] It should be noted that the tapping component 2 is not limited to one; there can be two or more tapping components 2. In some embodiments, at least two tapping components 2 can be arranged in the left-right direction or in the front-back direction. The tapping frequencies of the at least two tapping components 2 can be the same or different. In other words, at least two tapping components 2 can tap the surface to be cleaned simultaneously or tap the surface to be cleaned sequentially, thereby producing a better tapping cleaning effect.

[0055] In some embodiments, the drive device 3 is further provided with a drive disk 33, which is mounted on the drive shaft 31, and the eccentric shaft 32 is connected to the drive disk 33.

[0056] As shown in Figure 6, the drive device 3 is preferably, but not limited to, a rotary motor. The drive device 3 has a drive shaft 31 extending in the front-rear direction. The drive shaft 31 is the output shaft of the rotary motor. The drive shaft 31 is provided with a coaxial drive disk 33. An eccentric shaft 32 is provided at one end of the drive disk 33 opposite to the drive shaft 31. In some embodiments, the drive shaft 31 and the drive disk 33 are detachably connected, and the eccentric shaft 32 is integrally connected to the drive disk 33, thereby facilitating processing.

[0057] This disclosure provides two embodiments of the cleaning equipment's structure, but the cleaning equipment is not limited to these two embodiments.

[0058] The first embodiment of the cleaning equipment is described below with reference to Figures 1-6.

[0059] In the embodiments shown in Figures 2-5, the transmission mechanism 4 includes a transmission rod 41. The first end of the transmission rod 41 is pivotally connected to the eccentric shaft 32, and the second end of the transmission rod 41 is pivotally connected to the striking component 2. As shown in Figures 4 and 5, the transmission rod 41 has a first end and a second end arranged opposite each other in the vertical direction. The first end of the transmission rod 41 is the top end of the transmission rod 41 and is pivotally connected to the eccentric shaft 32 in the front-back direction. In some embodiments, the first end of the transmission rod 41 is sleeved on the outer periphery of the eccentric shaft 32, and the second end of the transmission rod 41 is the bottom end of the transmission rod 41 and is pivotally connected to the striking component 2 in the front-back direction. However, the first end of the transmission rod 41 in this application is not limited to being sleeved on the outer periphery of the eccentric shaft 32.

[0060] The tapping component 2 is driven by the transmission rod 41 and guided by the guide component 11 to move up and down. As shown in Figures 2 and 3, the guide component 11 guides and limits the tapping component 2 to move only in the up and down direction. When the drive device 3 is running, the eccentric shaft 32 drives the top end of the transmission rod 41 to rotate synchronously around the drive shaft 31, causing the transmission rod 41 to generate a displacement in the up and down direction, thereby driving the tapping component 2 to move in the up and down direction and extend and retract from the tapping and collecting device 12, forming a large contact tapping area with the surface to be cleaned.

[0061] In the embodiments shown in Figures 2-5, the striking component 2 includes a striking plate 21, a connecting seat 22, and a slider 23. The connecting seat 22 is disposed on the striking plate 21, and the slider 23 is disposed at both ends of the striking plate 21. The second end of the transmission rod 41 is pivotally connected to the connecting seat 22. Alternatively, the guiding component 11 includes a first guide plate 111 and a second guide plate 112. A groove 113 is formed between the first guide plate 111 and the second guide plate 112, and the slider 23 is slidably fitted in the groove 113.

[0062] As shown in Figures 4 and 5, the tapping component 2 includes a horizontally arranged tapping plate 21, the shape and size of which are adapted to the tapping and storage device 12. In some embodiments, the shape of the tapping plate 21 may be a rectangle extending in the left-right direction.

[0063] A connecting seat 22 is provided at the center of the striking plate 21 along the left-right direction, and the connecting seat 22 protrudes from the top surface of the striking plate 21. In some embodiments, the connecting seat 22 may be, but is not limited to, triangular. The top of the connecting seat 22 is pivotally connected to the bottom end of the transmission rod 41 in the front-back direction.

[0064] The body 1 is provided with guide components 11 on both the left and right sides of the tapping and storage device 12. The guide components 11 include a first guide plate 111 and a second guide plate 112. The first guide plate 111 and the second guide plate 112 extend in the vertical direction and are arranged at intervals in the front and back direction to form a vertically extending groove 113 between the first guide plate 111 and the second guide plate 112.

[0065] Both ends of the striking component 2 are equipped with sliders 23, which can slide up and down and fit into the same side groove in the left and right direction, thereby guiding the striking plate 21 to move stably in the up and down direction. At the same time, the first guide plate 111 and the second guide plate 112 on the left and right sides of the striking component 2 limit the striking component 2, so that the striking plate 21 and the striking and storing device 12 are always aligned vertically, preventing the striking component 2 from moving in the left and right direction and thus becoming misaligned with the striking and storing device 12.

[0066] Driven by the transmission rod 41, the tapping plate 21 moves vertically as a whole and can extend completely from the tapping and collecting device 12 to tap the surface to be cleaned, so that the tapping plate 21 and the surface to be cleaned form a large contact tapping area, resulting in a good tapping effect.

[0067] In the embodiments shown in Figures 2-5, the slapping component 2 further includes a counterweight 24, which is disposed on the slapping plate 21 and located on both sides of the connecting seat 22.

[0068] As shown in Figures 4 and 5, counterweights 24 are provided at both ends of the striking plate 21, and the counterweights 24 are detachably connected to the striking plate 21 via connectors. In some embodiments, the counterweights 24 are detachably connected to the striking plate 21 via bolts.

[0069] The counterweight 24 can increase the weight of the tapping component 2, so that the tapping plate 21 can generate a greater tapping force on the surface to be cleaned, thereby knocking out the debris deep in the surface to be cleaned and producing a stronger cleaning effect.

[0070] In some embodiments, the center of gravity formed by the counterweights 24 at the left and right ends is located at the center of the striking plate 21. In other words, the distance between the counterweights 24 at the left and right ends and the connecting seat 22 is equal. This keeps the striking plate 21 stable during movement and reduces frictional losses between the striking plate 21 and the slider 23 and the guide member 11.

[0071] In the embodiments shown in Figures 2-5, the first end of the transmission rod 41 is provided with an elongated hole 411, and the eccentric shaft 32 is pivotally and slidably fitted into the elongated hole 411.

[0072] As shown in Figures 4 and 5, the top end of the transmission rod 41 is provided with an elongated hole 411 extending in the vertical direction, and the eccentric shaft 32 can pivot and slide within the elongated hole 411.

[0073] During the extension and retraction of the tapping component 2 from the tapping and retracting device 12, the eccentric shaft 32 remains at the top of the elongated hole 411 of the transmission rod 41 in its natural state. When the surface to be cleaned is uneven, the protrusions of the surface will push up the extended tapping component 2, and the eccentric shaft 32 will move along the elongated hole 411 to the middle of the hole. This ensures the tapping effect of the tapping component 2 on the surface to be cleaned while also preventing damage from excessive impact forces between the eccentric shaft 32 and the transmission rod 41, and between the transmission rod 41 and the tapping component 2. In other words, the elongated hole 411 provides redundant space for the extension and retraction of the tapping component 2. This redundant space allows the cleaning equipment to be used on surfaces of different heights, such as carpets of different thicknesses.

[0074] The second embodiment of the cleaning equipment is described below with reference to Figures 6-12.

[0075] In the embodiment shown in Figures 8-12, a pivot 13 is provided inside the body 1, and the striking component 2 is pivotally connected to the pivot 13.

[0076] As shown in Figures 8 and 9, the body 1 has a pivot 13 extending in the front-back direction. The pivot 13 and the tapping and storing device 12 are arranged side by side in the vertical plane extending in the left-right direction. In other words, the pivot 13 can be located directly above the tapping and storing device 12, or above the left and right sides of the tapping and storing device 12. In some embodiments, the pivot 13 is located directly above the tapping and storing device 12. The tapping member 2 is pivotally connected to the pivot 13 in the front-back direction, so that the end of the tapping member 2 away from the pivot 13 can extend and retract from the tapping and storing device 12 as the tapping member 2 rotates around the pivot 13.

[0077] The transmission mechanism 4 includes a transmission seat 42 and a connecting rod 43. The transmission seat 42 is provided with a long groove 421, and the eccentric shaft 32 is pivotally and slidably fitted in the long groove 421 to drive the transmission seat 42 to move up and down. The transmission seat 42 is guided by the guide member 11. The first end of the connecting rod 43 is pivotally connected to the transmission seat 42, and the second end of the connecting rod 43 is pivotally and relatively slidably connected to the striking member 2 to drive the striking member 2 to swing around the pivot 13.

[0078] As shown in Figures 10 and 12, the transmission seat 42 is guided by the guide component 11 and can only move in the vertical direction. The rear end face of the transmission seat 42 is provided with a long groove 421 extending in the left-right direction. The eccentric shaft 32 can pivot and slide in the long groove 421. The connecting rod 43 has a first end and a second end arranged opposite to each other in the vertical direction. The first end of the connecting rod 43 is the top end of the connecting rod 43, and the second end of the connecting rod 43 is the bottom end of the connecting rod 43. The top end of the connecting rod 43 is pivotally connected to the transmission seat 42 in the front-back direction, and the bottom end of the connecting rod 43 is pivotally connected to the striking component 2 in the front-back direction.

[0079] When the drive unit 3 is running, the eccentric shaft 32 rotates around the drive shaft 31, thereby sliding along the long groove 421 and driving the transmission seat 42 to move in the up and down direction under the guidance of the guide component 11. The transmission seat 42 drives the connecting rod 43 to generate a displacement in the up and down direction. The connecting rod 43 drives the patting component 2 to rotate around the pivot 13 and extend and retract from the patting and receiving device 12, thereby patting the surface to be cleaned.

[0080] In the embodiment shown in Figures 8-12, the slapping component 2 includes a slapping plate 21 and a sliding rod 25. The first end of the sliding rod 25 is pivotally connected to the pivot 13, and the second end of the sliding rod 25 is connected to the slapping plate 21. A sliding sleeve 26 is provided on the sliding rod 25, and the sliding sleeve 26 can slide along the sliding rod 25. The second end of the connecting rod 43 is pivotally connected to the sliding sleeve 26.

[0081] As shown in Figures 11 and 12, the slide bar 25 extends in the left-right direction and has a first end and a second end that are arranged opposite to each other. The first end of the slide bar 25 is rotatably connected to the pivot 13 in the front-back direction, and the second end of the slide bar 25 is connected to the beater plate 21.

[0082] A sliding sleeve 26 is fitted onto the sliding rod 25, and the sliding sleeve 26 is pivotally connected to the bottom end of the connecting rod 43 in the front-back direction.

[0083] When the transmission seat 42 drives the top of the connecting rod 43 to move downward, the bottom of the connecting rod 43 drives the sliding sleeve 26 to move downward and drives the sliding sleeve 26 to slide along the sliding rod 25 away from the pivot 13, thereby driving the sliding rod 25 to rotate downward around the pivot 13 and causing the striking plate 21 to extend out of the striking and collecting device.

[0084] When the transmission seat 42 drives the top of the connecting rod 43 to move upward, the bottom of the connecting rod 43 drives the sliding sleeve 26 to move upward, and drives the sliding sleeve 26 to slide along the sliding rod 25 towards the pivot 13, thereby driving the sliding rod 25 to rotate upward around the pivot 13 and causing the striking plate 21 to retract into the striking and storing device.

[0085] It should be noted that by adjusting the shape of the tapping plate 21, when the tapping plate 21 taps the surface to be cleaned, the bottom surface of the tapping plate 21 can overlap with the surface to be cleaned or have an angle.

[0086] In the embodiment shown in Figures 8-12, the striking component 2 includes a first striking component 27 and a second striking component 28, which are located on both sides of the pivot 13. The connecting rod 43 includes a first connecting rod 431 and a second connecting rod 432. The first end of the first connecting rod 431 and the first end of the second connecting rod 432 are pivotally connected to the transmission seat 42, respectively. The second end of the first connecting rod 431 is pivotally connected to the sliding sleeve 26 of the first striking component 27, and the second end of the second connecting rod 432 is pivotally connected to the sliding sleeve 26 of the second striking component 28.

[0087] As shown in Figure 12, pivot 13 pivotally connects both the first striking component 27 and the second striking component 28. The first striking component 27 and the second striking component 28 are located on the left and right sides of pivot 13. The sliding sleeve 26 of the first striking component 27 is pivotally connected to the bottom end of the first connecting rod 431, and the sliding sleeve 26 of the second striking component 28 is pivotally connected to the bottom end of the second connecting rod 432. The top ends of the first connecting rod 431 and the second connecting rod 432 are pivotally connected to the transmission seat 42, respectively. In some embodiments, the transmission seat 42 has a connecting shaft that pivotally connects both the top ends of the first connecting rod 431 and the top ends of the second connecting rod 432. The top ends of the first connecting rod 431 and the second connecting rod 432 are located on the left and right sides of the connecting shaft. The first connecting rod 431 and the second connecting rod 432 extend from top to bottom and are inclined relative to each other.

[0088] The transmission seat 42 moves up and down once, causing the first connecting rod 431 and the second connecting rod 432 to move, so that the first tapping component 27 and the second tapping component 28 rotate around the pivot 13 at the same time. As a result, the tapping plate 21 of the first tapping component 27 and the tapping plate 21 of the second tapping component 28 tap the surface to be cleaned twice, producing a better cleaning effect.

[0089] In the embodiments shown in Figures 8-12, the first connecting rod 431 and the second connecting rod 432 are of the same length, so that the striking plates 21 of the first striking component 27 and the second striking component 28 strike synchronously. Each up-and-down movement of the transmission seat 42 causes the striking plates 21 of the first striking component 27 and the second striking component 28 to strike together once, generating a larger striking area and thus producing a better cleaning effect.

[0090] In other embodiments, the first link 431 and the second link 432 have different lengths so that the tapping plates 21 of the first tapping component 27 and the second tapping component 28 tap asynchronously. In some embodiments, the length of the first link 431 is shorter than the length of the second link 432. In this case, the tapping plate 21 of the second tapping component 28 taps the surface to be cleaned to a deeper depth and with greater force, and taps the surface before the tapping plate 21 of the first tapping component 27. The up-and-down movement of the transmission seat 42 drives the tapping plates 21 of the first tapping component 27 and the second tapping component 28 to tap the surface to be cleaned in sequence. The surface to be cleaned is tapped more frequently, and the tapping force is different, so that debris of different depths is tapped out, thereby producing a better cleaning effect.

[0091] In the embodiments shown in Figures 8-12, the striking component 2 further includes a counterweight (not shown) disposed on the striking plate 21.

[0092] Specifically, the counterweight is detachably mounted on the top surface of the tapping plate 21 via connectors such as bolts to increase the tapping force of the tapping plate 21 on the surface to be cleaned, thereby knocking out the debris deep in the surface to be cleaned and producing a stronger cleaning effect.

[0093] In the embodiment shown in Figures 8-12, the guiding component 11 includes a guide rod 114, and the transmission seat 42 is provided with a guide hole 422 that cooperates with the guide rod 114.

[0094] As shown in Figure 10, the guide rod 114 extends vertically, and the transmission seat 42 is provided with a guide hole 422 that extends vertically through it. The guide rod 114 passes through the guide hole 422 to guide the transmission seat 42 to move along the guide rod 114.

[0095] The guide rod 114 and the eccentric shaft 32 are arranged at intervals along the front-back direction to avoid interference between the eccentric shaft 32 and the guide rod 114 when the eccentric shaft 32 moves along the long groove 421.

[0096] In some embodiments, the detection device includes a detection component 5 and a detection switch 6, which are disposed inside the body 1. The detection component 5 triggers the detection switch 6 when the striking component 2 retracts to its limit position.

[0097] As shown in Figures 2-5, the detection component 5 and the detection switch 6 are both located inside the body 1. The detection component 5 moves synchronously with the striking component 2. When the striking component 2 extends out of the striking and storing device 12, the detection component 5 moves away from the detection switch 6. When the striking component 2 retracts into the striking and storing device 12, the detection component 5 moves closer to the detection switch 6. When the striking component 2 retracts back to its limit position, the detection switch 6 is triggered. Thus, the trigger signal of the detection switch 6 indicates whether the striking component 2 has retracted back to its limit position.

[0098] When the cleaning equipment is cleaning surfaces that do not require the tapping component 2 to tap, such as floors, or when the cleaning equipment is stopped or in standby mode, the trigger signal of the detection switch 6 ensures that the tapping component 2 retracts to its limit position and remains there, so as to avoid the tapping component 2 extending and causing collision damage and energy consumption.

[0099] In some embodiments, the detection component 5 is disposed on the eccentric shaft 32.

[0100] As shown in Figures 4-6, the elongated hole 411 extends through the transmission rod 41 in the front-back direction, and the eccentric shaft 32 is located inside the elongated hole 411. The detection component 5 is located at the end of the eccentric shaft 32 opposite to the drive disk 33 and at the front side of the transmission rod 41. In some embodiments, the detection component 5 is inserted into the end of the eccentric shaft 32.

[0101] The detection switch 6 is located on the trajectory of the detection component 5 as it rotates with the eccentric shaft 32, and has a detection channel for the detection component 5 to pass through. When the detection component 5 is located in the detection channel, the detection switch 6 is triggered.

[0102] It is understood that the detection component is not limited to being located on the eccentric shaft. In other embodiments, the detection component is located on any of the following: transmission rod, transmission seat, connecting rod, striking component, or counterweight.

[0103] In some embodiments, the cleaning device further includes a baffle 7 connected to the body 1 and movable between a closed position where the patting and storing device 12 is closed and an open position where the patting and storing device 12 is open.

[0104] As shown in Figures 7-9, the baffle 7 is connected to the body 1 and can move relative to the body 1 in the front-back direction. It has a closed position for closing the tapping and storing device 12 and an open position for opening the tapping and storing device 12. In some embodiments, the baffle 7 is disposed inside the body 1 and connected to a driver inside the body 1. The driver is located on one side of the tapping and storing device 12 in the front-back direction and drives the baffle 7 to move in the front-back direction. In some embodiments, the baffle 7 is a rectangle extending in the left-right direction. In the closed position, the baffle 7 covers the tapping and storing device 12 to close it. In the open position, the baffle 7 is located on one side of the tapping and storing device 12 in the front-back direction. In other words, the baffle 7 and the tapping and storing device 12 are arranged sequentially in the front-back direction to open the tapping and storing device 12.

[0105] When the baffle 7 opens the tapping and storage device 12, the tapping component 2 can extend and retract from the tapping and storage device 12. When the baffle 7 closes the tapping and storage device 12, the tapping component 2 retracts into the body 1 and is located above the baffle 7. The baffle 7 closes the tapping and storage device 12 to prevent debris from entering the body 1 through the tapping and storage device 12.

[0106] The drive unit 3, the driver, and the detection switch 6 are all electrically connected to the terminal of the cleaning equipment. When the cleaning equipment senses its position on the surface to be cleaned (e.g., a carpet) via infrared, camera, or light waves, the terminal of the cleaning equipment first sends a signal to the driver to move the baffle 7 to the open position, and then sends a signal to the drive unit 3 to drive the beating component 2 to perform the beating. When the cleaning equipment senses that it has detached from the surface to be cleaned, or when the cleaning equipment needs to stop, the terminal of the cleaning equipment controls the drive unit 3 to stop upon receiving a trigger signal from the detection switch 6, so that the beating component 2 remains in its retracted limit position, and then sends a signal to the driver to move the baffle 7 to the closed position.

[0107] In some embodiments, the distance S between the tapping and storing device 12 and the main brush compartment 14 along the moving direction of the body 1 is less than or equal to 150 mm. In some embodiments, the distance S between the tapping and storing device 12 and the main brush compartment 14 can be 150 mm, 120 mm, 100 mm, 80 mm, 50 mm, or 20 mm. As shown in Figures 1 and 7, this distance S is the distance between the rear side of the tapping and storing device 12 and the front side of the main brush compartment 14 in the front-rear direction in Figures 1 and 7.

[0108] During operation, the surface to be cleaned first passes under the tapping and collecting device 12 and is tapped by the tapping component 2, causing debris deep within the surface to be brought to the surface. Then, it passes under the main brush chamber 14, where the main brush sweeps the debris into the chamber through an opening, and is further collected by the dust collection port connected to the main brush chamber 14. If the distance S between the tapping and collecting device 12 and the main brush chamber 14 is greater than 150 mm, the debris cannot be promptly swept into the main brush chamber 14, affecting the cleaning effect.

[0109] In some embodiments, the length direction of the main brush chamber 14 is parallel to the length direction of the tapping and storing device 12, and the absolute value of the difference between the length L1 of the tapping and storing device 12 and the length L2 of the main brush chamber 14 is less than or equal to 50 mm. As shown in Figures 1 and 7, the length direction of the main brush chamber 14 is both left-right. The length L1 of the tapping and storing device 12 can be shorter or longer than the length L2 of the main brush chamber 14, and the difference between the longer and shorter lengths of the tapping and storing device 12 and the main brush chamber 14 is less than or equal to 50 mm. In some embodiments, the difference between the longer and shorter lengths of the tapping and storing device 12 and the main brush chamber 14 can be 50 mm, 45 mm, 30 mm, 10 mm, or 0 mm.

[0110] The length L1 of the tapping and collecting device 12 is related to the length L2 of the main brush compartment 14 to ensure that the debris tapped by the tapping component 2 is fully swept into the main brush compartment 14 by the main brush through the opening.

[0111] In some embodiments, the center line of the main brush compartment 14 in the left-right direction is collinear with the center line of the patting and collecting device 12 in the left-right direction.

[0112] The cleaning device of this embodiment has a beating and collecting device at the bottom of the machine body. The driving device drives at least a part of the beating component to extend and retract from the beating and collecting device through the transmission mechanism. This allows the cleaning device to beat out debris from the surface to be cleaned, such as carpets, so that it can be collected by the cleaning device. The detection device is used to detect when the beating component retracts to its limit position, ensuring that the beating component retracts to its limit position and remains there when the cleaning device is not in operation or when the cleaning device is stopped and in standby mode. Therefore, the cleaning device of this embodiment has a good cleaning effect.
