Description

Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a cleaning device and a cleaning device floor brush suction port adjustment assembly. Background Technology

[0002] Existing vacuum cleaners either have floor brush nozzles that are too large to handle large particles of debris, or too small to handle dirt and grime in scenarios requiring strong suction, such as carpets or crevices. In other words, vacuum cleaners have limited adaptability and cannot effectively handle multiple different cleaning scenarios at the same time.

[0003] Meanwhile, in the existing design of the front suction port of the adjustable floor brush, an additional drive and control device is added to the floor brush of the vacuum cleaner to adjust the size of the suction port. At the same time, the length of the screw of the drive device or the sliding part directly connected to the screw generally exceeds the length of the suction port, thus forming a sliding part movement stroke over the entire length range of the front suction port of the floor brush, resulting in more space occupation and an increased floor brush volume. Utility Model Content

[0004] The purpose of this application is to provide a cleaning device and a cleaning device floor brush suction port adjustment assembly, which can adjust the suction port size according to different cleaning scenarios to meet the cleaning needs of different cleaning scenarios.

[0005] To achieve the above objectives, this application provides a cleaning device comprising a floor brush and a main unit. The floor brush includes a floor brush body connected to the main unit, and a drive assembly and an adjustment assembly mounted on the floor brush body. The floor brush body has a first suction port located at the center of the front side of the floor brush body and a roller brush cavity communicating with the first suction port, the roller brush cavity being used to accommodate a roller brush. The drive assembly includes a motor, a drive rod connected to the motor, and a slider connected to the drive rod. The motor drives the drive rod to rotate and causes the slider to move horizontally within a groove. The adjustment assembly is connected to the slider and is used to adjust the opening area of ​​the first suction port. The motor, the slider, and the adjustment assembly are arranged sequentially laterally along the floor brush body, and the motor and the first suction port are located on opposite sides of the groove.

[0006] Optionally, a blocking element is provided between the first suction port and the motor; the motor and the blocking element are located at opposite ends of the slide groove, so that the slider is confined within the slide groove by the motor and the blocking element.

[0007] Optionally, when the slider is blocked by the motor and abuts against the motor, the slider drives the adjustment component to open the first suction port; when the slider is blocked by the blocking member and abuts against the blocking member, the slider drives the adjustment component to close the first suction port.

[0008] Optionally, the adjustment assembly includes a transmission component and a blocking component, wherein one end of the transmission component adjacent to the drive assembly is connected to the slider, and the transmission component is slidably connected to the floor brush body along a sliding direction parallel to the slider; the blocking component is slidably connected to the floor brush body along a sliding direction perpendicular to the transmission component, and has a first position with the first suction port open and a second position with the first suction port closed; when the slider abuts against the motor, the blocking component is in the first position, and when the slider abuts against the blocking component, the slider drives the blocking component to the second position via the transmission component.

[0009] Optionally, the adjustment assembly further includes a reset member connected to the blocking member, and the reset member provides a reset force for the blocking member to slide from the second position to the first position.

[0010] Optionally, the transmission member and the blocking member each have a guide ramp extending toward the other; when the blocking member is in the first position, the guide ramp of the transmission member abuts against the guide ramp of the blocking member; when the blocking member is in the second position, the bottom surface of the guide ramp of the transmission member abuts against the top surface of the guide ramp of the blocking member.

[0011] Optionally, the bottom surface of the guide ramp of the transmission component is provided with one of a mutually cooperating slot and a locking block, and the top surface of the guide ramp of the shielding component is provided with the other of a mutually cooperating slot and a locking block.

[0012] Optionally, the upper part of the shielding member has an upward and rearward opening groove and a sliding protrusion disposed on the front wall of the groove, and the lower part of the shielding member is a gate portion for closing the first suction port; the transmission member is at least partially located in the groove, and the transmission member has a sliding groove that is at least partially inclined, wherein the sliding protrusion is held in the sliding groove and slides up and down under the limitation of the sliding groove.

[0013] Optionally, the transmission member has an insert block at one end adjacent to the slider; the slider has an insert groove, and the insert block is inserted into the insert groove to connect the transmission member to the slider.

[0014] To achieve the above objectives, this application also provides a floor brush suction port adjustment assembly for a cleaning device. The adjustment assembly includes at least an adjustment component and a drive component located beside the adjustment component. The drive component includes a motor, a drive rod connected to the motor, and a slider threadedly connected to the drive rod. The motor drives the drive rod to rotate, and the drive rod causes the slider to slide within a preset area. The adjustment component includes a transmission member and a blocking member. One end of the transmission member adjacent to the drive component is connected to the slider. The blocking member moves along a sliding direction perpendicular to the slider. The preset area is formed between the motor and the blocking member. The motor, the slider, and the adjustment component are arranged sequentially in a transverse direction.

[0015] Therefore, the technical solution provided in this application has an adjustment component located at the first suction port position, which is connected to the slider. When the slider slides within the groove, the groove area formed between the first suction port and the motor is fully utilized to limit the slider's movement, thereby adjusting the opening height of the first suction port. This allows the first suction port to be adjusted to the corresponding opening height according to different cleaning scenarios, thus meeting the needs of various cleaning scenarios. Simultaneously, the length of the groove allows for adjustment of the opening area of ​​the first suction port, reducing the space occupied by the slider and preventing an increase in the size of the floor brush.

[0016] Furthermore, the sliding groove for the slider is confined between the motor and the first suction port. That is, throughout the entire stroke of the slider, it remains beside the first suction port. Compared to placing the slider above, in front of, or behind the adjustment assembly, this application's slider is positioned close to the motor, eliminating the need for the drive rod to extend excessively to connect with the slider, thus reducing the drive rod length and simplifying the structure of the drive assembly. Moreover, the slider and adjustment assembly are arranged laterally side-by-side on the front side of the floor brush body. This avoids affecting the layout of other components within the floor brush body and reduces the vertical height of the floor brush, preventing it from being too tall to access low-lying areas for cleaning and avoiding excessive restriction on the cleaning area.

[0036] With the diversification of market demand, the application range of vacuum cleaners continues to expand, covering various cleaning scenarios such as carpets, hard floors, fine dust, and large particles of debris. As a key component of the vacuum cleaner that comes into contact with the floor, the floor brush needs to be designed to adapt to different cleaning needs. For example, when dealing with larger particles of debris, the front end of the floor brush needs to have a sufficiently large gap to accommodate larger particles; while on carpets, the gap needs to be reduced to enhance suction power and sealing, improving the ability to adsorb dust from within the carpet.

[0037] Some related technologies add an extra suction port at the front of the floor brush to allow large particles of debris to be sucked in. However, when cleaning carpets or similar surfaces, a larger suction port can reduce suction power, affecting the ability to remove dust from carpets. Other technologies add an adjustment assembly to the suction port, requiring the user to bend over and adjust the size of the suction port. While this can be adapted to different cleaning scenarios, it requires manual adjustment by the user, sacrificing convenience and impacting the user experience.

[0038] To address this, this application incorporates an automatically adjustable assembly at the suction port. This assembly automatically adjusts to different cleaning scenarios, eliminating the need for manual adjustment by the user and improving the user experience. Furthermore, by confining the transmission slider between the motor and the suction port, the structure of the adjustment assembly is simplified, its size reduced, and its excessive size avoided interfering with the layout design of other components within the floor brush.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0040] This application provides a cleaning device comprising a floor brush 1000 and a main unit. The floor brush 1000 is pivotally connected to the main unit, allowing the main unit to rotate relative to the floor brush 1000. This enables the cleaning device to more easily clean under furniture or in narrow spaces, meaning the machine can tilt or even lie flat to accommodate cleaning needs at different heights. Furthermore, it caters to users of different heights, allowing for greater flexibility and convenience when using the floor scrubber, eliminating the need to bend over or squat. This design also helps reduce the physical strain on users during the cleaning process. A handle can be provided at the top of the machine for easy gripping, allowing users to move the machine and floor brush 1000 by holding the handle.

[0041] It should be noted that the cleaning equipment can be a vacuum cleaner with a suction function, which uses negative pressure suction to pick up dust and achieve cleaning. The vacuum cleaner can also be equipped with a roller brush, which physically sweeps up the dust, making it easier for the vacuum cleaner to suck in, thus more effectively removing dust and debris from the floor or surface. The cleaning equipment can also be a floor scrubber with both vacuuming and scrubbing functions, which can use suction to pick up dust alone, and can also use a roller brush and a running water cleaning system to scrub the floor. Of course, the cleaning equipment can also be other devices with a vacuuming function, and this application does not specifically limit this.

[0042] For details regarding the structure of the 1000 floor brush, please refer to [link / reference needed]. Figures 1 to 3 In one feasible implementation, the floor brush 1000 may include a floor brush body 100, which serves as the main body of the floor brush 1000 and primarily supports and protects other components of the floor brush 1000. The floor brush body 100 may have a first suction port 110 located at the front of the floor brush body 100. The first suction port 110 increases the size of the suction gap of the floor brush body 100 to accommodate larger particles. The floor brush body 100 may also have a roller brush cavity 120, which communicates with the first suction port 110. The roller brush cavity 120 is used to accommodate the roller brush, allowing larger particles sucked in through the first suction port 110 and dirt swept up by the roller brush to be sucked in together.

[0043] In practical applications, the floor brush body 100 may include an upper housing and a lower housing that are connected to each other. In this way, the remaining parts of the floor brush 1000 can be pre-installed on the upper housing or the lower housing, and then the upper housing or the lower housing can be connected to each other to facilitate the connection operation between the remaining parts of the floor brush 1000 and the floor brush body 100.

[0044] The floor brush 1000 may further include a drive assembly 200 and an adjustment assembly 300, wherein the drive assembly 200 includes a motor 210, a drive rod 220, and a slider 230. In this embodiment, the drive rod 220 may be a screw, and the motor 210 is located beside the first suction port 110 (e.g., Figure 3(As shown on the left or right side), the drive rod 220 is driven and connected to the motor 210, and the slider 230 is threadedly connected to the drive rod 220. The motor 210 drives the drive rod 220 to rotate, and through the drive rod 220, drives the slider 230 to slide within the preset area a. In practical applications, the motor 210 is fixed to the brush body 100. The motor 210 is connected to the slider 230 through the drive rod 220. The slider 230 slides within a groove provided on the brush body 100. The length of the groove for the slider 230 to slide laterally constitutes the preset area a. Thus, when the motor 210 drives the drive rod 220 to rotate, the slider 230, under the limitation of the groove and the action of the threaded drive, achieves left and right sliding within the preset area a.

[0045] An adjustment component 300 is located at the first suction port 110 and is connected to the slider 230. The motor 210, slider 230, and adjustment component 300 are arranged sequentially along the transverse side of the floor brush body 100. The motor 210 and the first suction port 110 are located on opposite sides of the slide groove. When the slider 230 slides within the preset area a, the slider 230 can drive the adjustment component 300 to adjust the opening height of the first suction port 110, thereby adjusting the opening area of ​​the first opening 110. This allows the first suction port 110 to be adjusted to the corresponding opening height according to different cleaning scenarios, thus meeting the needs of different cleaning scenarios while ensuring cleaning effectiveness.

[0046] The preset area 'a' is located between the motor 210 and the first suction port 110. That is, throughout the entire stroke of the slider 230, it remains beside the first suction port 110. Compared to placing the slider 230 above, in front of, or behind the adjustment assembly 300, this application's placement of the slider 230 close to the motor 210 eliminates the need for the drive rod 220 to extend excessively to connect with it, reducing the length of the drive rod 220 and simplifying the structure of the drive assembly 200. Furthermore, the slider 230 and the adjustment assembly 300 are arranged laterally side-by-side on the front side of the floor brush body 100. This arrangement does not affect the layout of other components within the floor brush body 100 and reduces the vertical height of the floor brush 1000, preventing it from being too tall to access low-lying areas for cleaning and avoiding excessive restrictions on the cleaning area.

[0047] In practical applications, the cleaning equipment may be equipped with control buttons, which the user operates to control the motor 210, thereby adjusting the opening height of the first suction port 110. And / or, the cleaning equipment may be equipped with a dirt detection sensor, which detects the size of the dirt and adjusts the opening height of the first suction port 110 accordingly.

[0048] like Figure 3As shown, in one feasible implementation, a blocking member 400 may be provided between the first suction port 110 and the motor 210. The motor 210 and the blocking member 400 are located at opposite ends of the preset area. In other words, the motor 210 and the blocking member 400 restrict the preset area to be located at both ends in the lateral direction, thereby confining the slider 230 within the preset area a by the motor 210 and the blocking member 400, and preventing the blocking member 400 from detaching from the preset area a during operation.

[0049] In practical applications, the blocking component 400 can be integrally formed with the upper or lower shell of the brush body 100, thereby simplifying the production process. Alternatively, the blocking component 400 can be designed separately from the brush body 100 and then connected to it.

[0050] The aforementioned motor 210 can be a servo motor, which uses precise position control to make the slider 230 slide within the preset area a. Furthermore, when the motor 210 is a servo motor, the slider 230 can stop at any position in the lateral direction within the preset area a, thereby driving the adjustment component 300 to infinitely adjust the opening height of the first suction port 110, so that the first suction port 110 can be adjusted to any opening size.

[0051] The aforementioned motor 210 can also be a general-purpose motor, or in other words, the motor 210 may lack precise position control or have poor position control capabilities. Correspondingly, such as... Figure 3 and Figure 4 As shown, in this embodiment, the cleaning equipment may further include a control board 500. The motor 210 is electrically connected to the control board 500. The control board 500 receives signals from the motor 210, such as current, speed, or start / stop indicator lights, and sends control signals to the motor 210. The control board 500 is configured to determine the magnitude of the load current of the motor 210 and a preset current. When the slider 230 is blocked by the motor 210 or the blocking member 400 during sliding, causing the load current of the motor 210 to exceed the preset current, the control board 500 controls the motor 210 to stop running. This allows the slider 230 to slide between the position abutting the motor 210 and the position abutting the blocking member 400, i.e., the slider 230 slides within the preset area a. Thus, the motor 210 can be a general-purpose motor, which does not need to have high position control capability. The slider 230 can slide within the preset area a through the control logic of the control board 500 in conjunction with the motor 210. Compared with a servo motor, this significantly reduces production costs.

[0052] In practical applications, since the motor 210 can only stop moving when the slider 230 is blocked by the motor 210 or the blocking member 400, the slider 230 only has a contact position with the motor 210 and a contact position with the blocking member 400. Thus, the slider 230 drives the adjustment component 300 to open and close the first suction port 110.

[0053] Specifically, when slider 230 is blocked by motor 210 and comes into contact with motor 210, slider 230 can drive adjustment component 300 to open first suction port 110. When slider 230 is blocked by blocking member 400 and comes into contact with blocking member 400, slider 230 can drive adjustment component 300 to close first suction port 110.

[0054] Of course, when slider 230 is blocked by motor 210 and comes into contact with motor 210, slider 230 can also drive adjustment component 300 to close the first suction port 110. When slider 230 is blocked by blocking member 400 and comes into contact with blocking member 400, slider 230 can drive adjustment component 300 to open the first suction port 110.

[0055] It should be noted that when the adjustment component 300 closes the first suction port 110, it does not mean that the adjustment component 300 is in complete contact with the ground. A certain gap can be reserved between the adjustment component 300 and the ground so that small particles of dirt can be sucked up through the gap.

[0056] To simplify the specific structure of the adjustment component 300, this application preferably provides an implementation in which the slider 230 can drive the adjustment component 300 to open the first suction port 110 when the slider 230 is blocked by the motor 210 and comes into contact with the motor 210, and the following description will also follow accordingly.

[0057] Specifically, such as Figure 2 , Figure 3 and Figure 5 As shown, in one feasible embodiment, the adjustment assembly 300 may include a transmission member 310 and a blocking member 320. The transmission member 310 is connected to the slider 230 at one end adjacent to the drive assembly 200. The transmission member 310 is slidably connected to the floor brush body 100 along a sliding direction parallel to the slider 230, meaning the sliding direction of the transmission member 310 is parallel to the sliding direction of the slider 230. The blocking member 320 is slidably connected to the floor brush body 100 along a sliding direction perpendicular to the transmission member 310, and has a first position with the first suction port 110 open and a second position with the first suction port 110 closed. When the slider 230 abuts against the motor 210, the blocking member 320 is in the first position, opening the first suction port 110. When the slider 230 abuts against the blocking member 400, the slider 230 drives the blocking member 320 to the second position via the transmission member 310, closing the first suction port 110.

[0058] In this embodiment, the sliding direction of the slider 230 and the transmission member 310 can be the horizontal direction, and the sliding direction of the blocking member 320 is the vertical direction. The blocking member 320 opens and closes the first suction port 110 by sliding up and down.

[0059] In practical applications, the transmission component 310 and the shielding component 320 can be directly slidably connected to the upper or lower shell of the floor brush body 100, or they can be slidably connected to components that are fixedly connected to the floor brush body 100. This application does not make any specific limitations on this.

[0060] Regarding how to drive the blocking member 320 to switch between a first position and a second position by sliding it up and down, this application provides two possible embodiments for reference.

[0061] Example 1, such as Figures 5 to 8 As shown, the adjustment assembly 300 also includes a reset member 330, which is connected to the blocking member 320 and provides a reset force for the blocking member 320 to slide from the second position to the first position. That is, the blocking member 320 is driven by the transmission member 310 to switch from the first position to the second position, and is switched from the second position to the first position by the reset member 330.

[0062] Specifically, the transmission component 310 and the blocking component 320 are arranged vertically. Each of the transmission component 310 and the blocking component 320 has a guide ramp 340 extending towards the other. The guide ramp 340 has a guide ramp surface, which is downward and inclined towards the slider 230. Thus, as the slider 230 slides from the position abutting against the motor 210 to the position abutting against the blocking component 400, the slider 230 drives the transmission component 310 to move to the right. The guide ramp surface of the transmission component 310 cooperates with the guide ramp surface of the blocking component 320 and applies a force to the guide ramp surface of the blocking component 320, causing the blocking component 320 to slide downward, thereby moving the blocking component 320 from the first position to the second position to close the first suction port 110. As the slider 230 slides from the position abutting against the blocking member 400 to the position abutting against the motor 210, the slider 230 drives the transmission member 310 to move to the left, reducing or removing the force applied to the guide ramp of the blocking member 320. Simultaneously, the reset member 330 drives the blocking member 320 to move upwards, thereby moving the blocking member 320 from the second position to the first position to open the first suction port 110. When the blocking member 320 is in the first position, the guide ramp of the guide ramp block 340 of the transmission member 310 and the guide ramp block 340 of the blocking member 320 can abut or separate.

[0063] In practical applications, the reset component 330 can be a spring or other components with elastic deformation capabilities. Taking the reset component 330 as a spring as an example, the front or rear of the blocking component 320 has a protruding outer edge, the top end of the spring abuts against the outer edge, and the bottom end of the spring abuts against the floor brush body 100. When the blocking component 320 moves from the first position to the second position, the spring is compressed and accumulates energy. When the blocking component 320 moves from the second position to the first position, the spring releases energy, pushing the blocking component 320 upward to open the first suction port 110.

[0064] To improve the stability of the shield 320 when it is in the second position and the first suction port 110 is closed. For example... Figure 8 As shown, in one feasible embodiment, the guide ramp 340 of the shield 320 has a top surface that engages with its guide ramp, and the guide ramp 340 of the transmission member 310 has a bottom surface that engages with its guide ramp; the top and bottom surfaces are horizontally arranged. When the shield 320 is in the second position, the bottom surface of the guide ramp 340 of the transmission member 310 can abut against the top surface of the guide ramp 340 of the shield 320, so that the force exerted by the transmission member 310 on the shield 320 is vertically downward, increasing the resistance force of the transmission member 310 on the shield 320 and ensuring the stability of the shield 320 in closing the first suction port 110.

[0065] Furthermore, such as Figure 6 As shown, the top surface of the guide ramp 340 of the shielding member 320 is provided with a slot 341, and the bottom surface of the guide ramp 340 of the transmission member 310 is provided with a locking block 342. Alternatively, the top surface of the guide ramp 340 of the shielding member 320 is provided with a locking block 342, and the bottom surface of the guide ramp 340 of the transmission member 310 is provided with a slot 341. In this way, when the bottom surface of the guide ramp 340 of the transmission member 310 and the top surface of the guide ramp 340 of the shielding member 320 abut against each other, the locking block 342 engages with the slot 341, improving the bonding force between the top and bottom surfaces, preventing the top and bottom surfaces from accidentally separating due to shaking, and further improving the stability of the shielding member 320 in closing the first suction port 110.

[0066] Example 2, as follows Figure 2 , Figure 3 , Figures 9 to 11As shown, the blocking member 320 is driven by the transmission member 310 to switch from the first position to the second position and from the second position to the first position. Specifically, the blocking member 320 has an upper part and a lower part. The upper part has an upward and rearward opening groove 321 and a sliding protrusion 322 disposed on the front wall of the groove 321. The lower part is configured as a gate portion 323 to close the first suction port 110. The transmission member 310 is at least partially located in the groove 321. The transmission member 310 has a sliding groove 311 that is at least partially inclined. The inclined portion of the sliding groove 311 can be inclined downward and towards the slider 230. The sliding protrusion 322 is held in the sliding groove 311. When the slider 1230 drives the transmission member 310 to slide left and right, the sliding protrusion 322 moves up and down under the combined action of the limiting position of the sliding groove 311 and the sliding limiting position of the blocking member 320, thereby driving the blocking member 320 to slide up and down.

[0067] In this embodiment, there can be multiple sliding protrusions 322, which are spaced apart along the length of the groove 321. Correspondingly, there can also be multiple sliding grooves 311, with the number of grooves 311 not less than the number of sliding protrusions 322, and each sliding protrusion 322 is inserted into a corresponding sliding groove 311. In this way, when the transmission member 310 slides left and right, the multiple sliding protrusions 322 can drive the blocking member 320 to slide up and down, thereby ensuring the stability of the blocking member 320's up and down sliding.

[0068] In practical applications, the sliding groove 311 can be a blind hole or a through hole that passes through the transmission component 310. Taking the sliding groove 311 as a through hole as an example, the free end of the sliding protrusion 322 can be provided with a retaining edge that extends radially outward by a certain distance. When the sliding protrusion 322 is inserted into the sliding groove 311, the retaining edge can pass through the sliding groove 311 and abut against the back of the transmission component 310, thereby connecting the transmission component 310 and the blocking component 320 and preventing the sliding protrusion 322 from falling out of the sliding groove 311.

[0069] Regarding the specific structure of slider 230, as follows: Figure 9 and Figure 10 As shown, in one feasible embodiment, the top surface of the slider 230 is provided with an embedding groove 231, and correspondingly, the end of the transmission member 310 adjacent to the slider 230 is provided with an embedding block 312, which is inserted into the embedding groove 231 to connect the transmission member 310 and the slider 230.

[0070] In practical applications, the top surface of the slider 230 and the side adjacent to the transmission component 310 are both provided with openings. The insert block 312 can be inserted into the insert groove 231 through the opening on the top surface of the insert groove 231 and overlap the opening on the side of the insert groove 231 adjacent to the transmission component 310. The insert block 312 does not protrude from the top surface of the slider 230, thereby further reducing the volume of the drive assembly 200. The bottom surface of the slider 230 can also be provided with a slide rail to ensure that the slider 230 slides back and forth in the left and right direction.

[0071] Based on the same inventive concept, this application also provides an adjustment assembly for the suction port of a cleaning device's floor brush. The adjustment assembly includes at least an adjustment component 300 and a drive component 200 located beside the adjustment component 300. The drive component 200 includes a motor 210, a drive rod 220 connected to the motor 210, and a slider 230 threadedly connected to the drive rod 220. The motor 210 drives the drive rod 220 to rotate and drives the slider 230 to slide within a preset area. The adjustment component 300 includes a transmission component 310 and a blocking component 320. One end of the transmission component 310 adjacent to the drive component 200 is connected to the slider 230. The blocking component 320 moves in a direction perpendicular to the sliding direction of the slider 230. A preset area is formed between the motor 210 and the blocking component 320. The motor 210, the slider 230, and the adjustment component 300 are arranged in a transverse direction.

[0072] It should be noted that the specific structures of the drive assembly 200 and the adjustment assembly 300 can be found in the detailed descriptions in the above embodiments, and will not be repeated here. The adjustment assembly can be applied to the suction port of a vacuum cleaner or floor scrubber to control the size of the suction port opening. Of course, the adjustment assembly can also be applied to other areas with openings to adjust the size of the opening.

[0073] The following section will provide a detailed explanation using a vacuum cleaner as an example, taking a specific application scenario as an example.

[0074] Application Scenario 1

[0075] The user purchased a vacuum cleaner with an openable suction port on the front of the floor brush.

[0076] When a user vacuums the floor, the suction port is initially closed, and dust on the floor is sucked into the vacuum cleaner by the high-speed airflow generated by the floor brush. When the vacuum cleaner encounters larger particles, the dirt sensor on the front of the floor brush detects their presence. Subsequently, the drive component inside the floor brush activates the adjustment component to open the suction port, allowing the larger particles to be sucked into the vacuum cleaner. If the dirt sensor does not detect larger particles within a preset time period, the drive component inside the floor brush activates the adjustment component to close the suction port, maintaining suction power at the floor brush and thus ensuring effective cleaning under normal conditions.
