Description

Technical Field

[0001] This utility model relates to the field of cleaning instrument technology, and in particular to an automatic telescopic tapping bar and cleaning equipment. Background Technology

[0002] Dust mite removers, as small household appliances, are widely used in home cleaning, primarily to remove dust and dust mites from furniture such as beds and sofas, and also have a sterilization function. Their core working principle relies on three steps: "beating, vacuuming, and sterilization." With technological advancements, current mainstream dust mite removers have upgraded from the early vibrating blocks to using roller brushes with rubber strips or bristles for beating, thus improving cleaning efficiency and effectiveness.

[0003] Currently available mite removers typically have fixed tapping strips on their roller brushes, meaning their extension is not adjustable. Therefore, when used on surfaces of varying softness, such as soft blankets versus hard sofas or mattresses, the degree of contact between the tapping strips and the surface differs, affecting the tapping effect. For example, on soft surfaces, excessive sinking may lead to over-tapping, while on hard surfaces, insufficient contact may reduce the tapping effect. Furthermore, the fixed roller brush diameter directly limits the adaptability and flexibility of the mite remover on different surface types. Users cannot optimize the tapping force and effect by adjusting the device when dealing with furniture surfaces of different materials, thus reducing the user experience.

[0004] The root cause of the above problems lies in the fact that the design of mite removers does not adequately consider the differences between various cleaning surfaces. Specifically, because the length of the roller brush and its tapping strips is fixed, their extension and the degree of interaction with the cleaning surface cannot be automatically adjusted according to the surface's softness. When the mite remover is used on surfaces of varying hardness, this design causes the actual contact area between the tapping strips and the cleaning surface to change, thus affecting the final cleaning effect and user experience.

[0005] Therefore, it is necessary to design a new structure to improve the performance of the mite remover in various environments, adapt to different surface characteristics, and solve the technical problems in the existing technology where the diameter of the mite remover's roller brush is fixed and the beating force is fixed and cannot be adjusted, and the beating effect of the mite remover varies when cleaning surfaces of different hardness due to the fixed extension of the beating strip.

The dust sensor is used to sense the amount of dust in the air duct opening during the operation of the whole machine, so as to adjust the rotation speed of the roller brush bar through the dust sensor.

[0017] The advantages of this invention compared to existing technologies are as follows: This invention integrates a beating strip, a roller brush, and a telescopic structure into one unit.

[0040] Current mite removers on the market fail to adequately consider the differences between various cleaning surfaces. This is primarily due to the fixed, non-adjustable length of the roller brush and its tapping strip 10, leading to over-tapping or insufficient contact on both soft and hard surfaces, thus affecting cleaning effectiveness and user experience. This fixed design limits the adaptability and flexibility of mite removers on different surface types, failing to meet users' needs for optimized tapping force and effect. Therefore, there is a need in the existing technology for mite removers that can automatically adjust the extension of the tapping strip 10 and the diameter of the roller brush according to surface hardness to improve cleaning efficiency and user experience.

[0041] Therefore, this utility model provides an automatic telescopic tapping bar 10 and a cleaning device to improve the performance of the mite remover in various environments, adapt to different surface characteristics, and solve the problems in the prior art where the diameter of the mite remover's roller brush is fixed and the tapping force is fixed and cannot be adjusted, and the tapping effect of the mite remover is different when cleaning surfaces of different hardness because the extension amount of the tapping bar 10 is fixed.

[0042] Specifically, the automatic telescopic tapping bar 10 includes a tapping bar 10, a roller brush 20, a telescopic structure 30, and a fixing structure. By setting a placement groove 21 on the roller brush 20 and assembling the tapping bar 10 into the placement groove 21, the telescopic structure 30 adjusts the internal depth of the tapping bar 10, thus achieving automatic adjustment of the extension amount of the tapping bar 10. This solves the problem in the prior art where the cleaning effect on surfaces of different hardness is different due to the fixed and non-adjustable diameter of the roller brush and the tapping force. In addition, the cleaning device also integrates a drive structure and a dust sensor 100, which can intelligently adjust the rotation speed of the roller brush 20 according to the amount of dust in the air duct 61 during operation, further optimizing the cleaning efficiency and user experience of the mite remover.

[0043] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0044] Please see Figures 1 to 3 The aforementioned automatic telescopic tapping bar 10 includes: tapping bar 10, roller brush 20 and telescopic structure 30. The roller brush 20 is provided with a placement groove 21. One end of the tapping bar 10 is fitted into the placement groove 21. The telescopic structure 30 is fitted into the placement groove 21 and is used to adjust the depth of the tapping bar 10 within the placement groove 21.

[0045] The main purpose of the automatic telescopic tapping strip 10 structural design is to solve the problems of fixed diameter of the roller brush and non-adjustable tapping force in the existing technology of mite removal device. In particular, when facing cleaning surfaces of different hardness, the fixed extension of the tapping strip 10 will lead to different tapping effects.

[0046] Specifically, the tapping strip 10 is the part that directly contacts the cleaning surface and is responsible for removing dust mites through rotation and tapping motions. The roller brush 20 is an assembly with a placement slot 21 for mounting the tapping strip 10. The roller brush 20 is part of the overall roller brush assembly 90 and is capable of rotation to achieve the tapping function. The telescopic structure 30 is fitted within the placement slot 21 and is mainly used to adjust the internal depth of the tapping strip 10, i.e., to control the length of the tapping strip 10 extending from the placement slot 21. This structure allows the tapping strip 10 to automatically adjust its extension as needed, thereby adapting to cleaning surfaces of different hardness.

[0047] A placement groove 21 is provided on the roller brush 20, and one end of the beater strip 10 is fitted into the placement groove 21. This design allows the beater strip 10 to be completely retracted into the roller brush 20 when not in use, while it can be partially or fully extended during operation as needed. The telescopic structure 30 is not only used to adjust the built-in depth of the beater strip 10, but also, through a combination of mechanisms such as a spring system, to dynamically adjust the extension amount of the beater strip 10 according to changes in motor speed (which in turn affects centrifugal force). This allows the device to maintain a stable beating effect on surfaces of varying hardness. Through a dust sensing device or other types of sensors (such as pressure sensors or far-infrared sensors), the system can automatically sense the state of the surface to be cleaned and adjust the motor speed accordingly, thereby indirectly controlling the roller brush diameter and the beating force.

[0048] In one embodiment, please refer to Figures 1 to 3 The aforementioned tapping strip 10 has a horizontal plate 11 at one end, which is installed in the placement groove 21, and one end of the telescopic structure 30 abuts against the horizontal plate 11.

[0049] In Embodiment 1, to ensure that the tapping strip 10 can be stably assembled in the placement groove 21 on the roller brush 20 and that the extension amount can be adjusted as needed, a horizontal plate 11 is provided at one end of the tapping strip 10. By providing the horizontal plate 11 at one end of the tapping strip 10, the tapping strip 10 can be more securely assembled in the placement groove 21, reducing loosening or displacement caused by high-speed rotation. The horizontal plate 11 serves as a connection point, abutting against one end of the telescopic structure 30, thereby achieving precise control over the extension length of the tapping strip 10.

[0050] In one embodiment, please refer to Figures 1 to 3 The other end of the aforementioned telescopic structure 30 abuts against the upper wall of the placement groove 21.

[0051] In Embodiment 1, the telescopic structure 30 is a key component for automatically adjusting the extension amount of the striking bar 10, and it is typically made of a spring or other elastic material. The telescopic structure 30 operates as follows:

[0052] One end of the telescopic structure 30 directly contacts the horizontal plate 11 on the beater bar 10. When the motor speed changes, causing a change in centrifugal force, the telescopic structure 30 adjusts the extension length of the beater bar 10 according to the change in force. For example, at high speed, the centrifugal force increases, compressing the telescopic structure 30 (such as a spring), causing the beater bar 10 to extend further; conversely, at low speed, the telescopic structure 30 returns to its original position, and the beater bar 10 retracts.

[0053] The other end of the telescopic structure 30 is fixed to the upper wall of the placement groove 21. This design ensures that the telescopic structure 30 provides a reaction force in any state, helping to maintain the position and stability of the tapping strip 10. At the same time, it also ensures that the extension length of the tapping strip 10 can be flexibly adjusted according to actual needs to adapt to cleaning surfaces of different hardness.

[0054] Through the above design, the tapping strip 10 can automatically adjust its extension length under different operating conditions, thereby adjusting the effective diameter and tapping force of the roller brush. This mechanism not only solves the limitation of the fixed roller brush diameter in existing technologies, but also significantly improves the cleaning effect of the mite remover on various surfaces. In particular, when combined with intelligent control systems such as dust sensors, the entire device can automatically optimize operating parameters based on real-time detected environmental conditions, further enhancing the user experience and cleaning efficiency.

[0055] Please see Figures 4 to 9 The aforementioned automatic telescopic flapping bar 10 also includes a fixing structure, which is assembled in the placement groove 21.

[0056] In Embodiments 2 and 3, a specially designed fixing structure is used to ensure that the tapping bar 10 can automatically adjust its extension according to the speed change of the roller brush motor 91, while maintaining its stability and reliability. This fixing structure is assembled in the placement groove 21 to support and guide the tapping bar 10 and its related components, such as springs, to move precisely.

[0057] In one embodiment, please refer to Figures 4 to 6 The aforementioned fixing structure is located on both sides of the beater bar 10, and the fixing structure is located above the horizontal plate 11. The other end of the telescopic structure 30 abuts against the side of the fixing structure near the horizontal plate 11.

[0058] In one embodiment, please refer to Figures 4 to 6 The aforementioned fixing structure abuts against the upper wall of the placement groove 21.

[0059] In one embodiment, please refer to Figures 4 to 6 The aforementioned fixing structure includes two side plates 40 and a connecting plate 41. The two ends of the connecting plate 41 are respectively connected to the two side plates 40, and the two side plates 40 are respectively located on both sides of the beater bar 10.

[0060] In Embodiment 2, the fixing structure mainly consists of two side plates 40 and a connecting plate 41. The two side plates 40 are located on both sides of the striking bar 10, while the connecting plate 41 connects the top of the two side plates 40 to form an integral frame. This design not only provides physical constraint and support for the striking bar 10, but also ensures that it can move freely within a predetermined range without deviating from the track.

[0061] In this embodiment, the position of the fixing structure is particularly important. It is located above the horizontal plate 11 at one end of the beater bar 10, and one end of the telescopic structure 30 contacts the horizontal plate 11, while the other end abuts against the side of the fixing structure closest to the horizontal plate 11. This arrangement ensures that when changes in motor speed cause changes in centrifugal force, the telescopic structure 30 can effectively push or pull back the beater bar 10, thereby adjusting its extension length.

[0062] The fixing structure abuts against the upper wall of the placement groove 21: it directly contacts the upper wall of the placement groove 21. This not only provides additional support points to prevent displacement of the fixing structure itself, but also ensures that the beater bar 10 maintains the correct posture and movement trajectory even under high-speed rotation conditions.

[0063] When the mite remover is running, users can select different motor speed settings based on the hardness of the surface being cleaned. At high speeds, due to increased centrifugal force, the beater bar 10 extends further due to spring compression, increasing the effective diameter of the brush and the beating force on the cleaned surface. At low speeds, the spring returns to its original position, and the beater bar 10 retracts, reducing the brush diameter and beating force. Combined with a dust sensor or other sensors (such as pressure sensors or far-infrared sensors), the system can automatically detect the current cleaning environment and dynamically adjust the motor speed accordingly, thus achieving a more intelligent operating experience.

[0064] In this embodiment, the two side plates 40 and the connecting plate 41 form a horizontal C-shaped fixing plate. One end of the spring is fixed to the tapping strip 10 or the roller brush 20, and the other end is fixed to the fixing structure. The entire tapping strip 10 can be assembled onto the roller brush 20. Adding the fixing structure allows the tapping strip 10 assembly to be better fitted onto the roller brush 20.

[0065] Specifically, to further optimize the assembly stability and operational reliability of the beater bar 10, a horizontal C-shaped fixing plate structure was designed. This design not only improves the ease of installation of the beater bar 10 assembly on the roller brush 20, but also enhances its overall stability, ensuring high-efficiency performance under different working conditions.

[0066] The C-shaped fixing plate consists of two side plates 40 and a connecting plate 41. The two side plates 40 are located on both sides of the beater bar 10, and the connecting plate 41 connects the tops of the two side plates 40 to form a shape similar to the letter "C". This C-shaped structure provides a stable support frame for the beater bar 10, allowing it to move freely within a predetermined range without deviating from the track or experiencing unnecessary offset.

[0067] In Embodiment 2, one end of the telescopic structure 30 is fixed to the striking strip 10 or the roller brush, while the other end is fixed to the C-shaped fixing plate. Specifically, the telescopic structure 30 is connected directly to the striking strip 10 at one end via fixing points at both ends, and the other end is fixed to an appropriate position on the C-shaped fixing plate. This design effectively utilizes the elastic characteristics of the spring, adjusting the extension of the striking strip 10 according to the change in centrifugal force when the motor speed changes, thereby dynamically adjusting the effective diameter and striking force of the roller brush.

[0068] Thanks to the C-shaped fixing plate design, the entire tapping bar 10 can be more easily assembled onto the roller brush 20. This not only simplifies the assembly steps in the production process and reduces labor costs, but also improves product reliability and consistency. Furthermore, the C-shaped fixing plate provides additional support for the tapping bar 10 assembly, preventing loosening or misalignment during high-speed rotation.

[0069] When the mite remover is running, users can select different motor speed settings according to the hardness of the surface being cleaned. At high speeds, increased centrifugal force compresses the spring, causing the tapping strip 10 to extend further, increasing the effective diameter of the roller brush and the tapping force on the cleaned surface. At low speeds, the spring returns to its original position, and the tapping strip 10 retracts, reducing the roller brush diameter and tapping force. The C-shaped fixing plate design provides a robust support frame for the tapping strip 10 assembly, ensuring it maintains the correct posture and movement trajectory under different working conditions. This design also improves assembly efficiency and product consistency, contributing to a better user experience.

[0070] In summary, the horizontal C-shaped fixing plate structure adopted in this embodiment, through the ingenious combination of springs and fixing plates, not only solves the problems of fixed brush diameter and unadjustable beating force in traditional mite removers, but also significantly improves the cleaning efficiency and effect of the device on various material surfaces. This design embodies a high degree of innovation and practicality, and is of great significance for improving existing technologies.

[0071] In one embodiment, please refer to Figures 7 to 9 The aforementioned fixing structure includes a fixing housing 50, which has openings on both end faces and a strip hole 51 on one side. One end of the striking strip 10 passes through the strip hole 51 and is assembled inside the fixing housing 50. The other end of the telescopic structure 30 abuts against the side of the fixing housing 50 with the strip hole 51.

[0072] The design of the fixed structure optimizes the assembly method of the beater bar 10 assembly by introducing a special fixed housing 50, thereby improving assembly stability and operational reliability.

[0073] The mounting housing 50 has two end faces, each with an opening, which allows the tapping bar 10 to be installed into the mounting housing 50 through the side opening. In addition, a strip-shaped hole 51 is provided on one side of the mounting housing 50, which is designed to allow the tapping bar 10 to move in and out flexibly and adjust its position.

[0074] Specifically, one end of the tapping bar 10 is inserted through an opening and eventually fitted into the fixed housing 50. The other side of the tapping bar 10 passes through the strip-shaped hole 51. This design allows the tapping bar 10 to extend and retract freely within a certain range, while ensuring that it will not easily detach or shift.

[0075] In Embodiment 3, the telescopic structure 30 actually refers to a spring, one end of which is connected to the tapping strip 10 / roller brush, and the other end is fixed to the fixed housing 50. This spring system not only provides the necessary elastic support, allowing the tapping strip 10 to automatically adjust its extension according to different working conditions (such as changes in motor speed), but also ensures that the tapping strip 10 assembly can work effectively on cleaning surfaces of different hardness.

[0076] Thanks to its unique fixed housing 50 design, the tapping strip 10 can be flexibly adjusted in length to adapt to different materials and hardnesses of cleaning surfaces. Whether it's a hard floor or a soft carpet, it achieves ideal tapping results. By precisely controlling the extension of the tapping strip 10, the effective diameter of the roller brush and the tapping force on the cleaning surface can be effectively increased, thereby improving the overall cleaning efficiency and effect of the mite remover. The fixed housing 50 provides a robust support frame for the tapping strip 10, reducing the risk of wear and damage due to long-term use and extending the device's lifespan.

[0077] In summary, the fixed housing 50 and its matching telescopic structure 30 designed in this embodiment, by innovatively combining physical structure and mechanical principles, not only solve the problems of fixed brush diameter and non-adjustable beating force in traditional mite removers, but also significantly improve the cleaning efficiency and effect of the device on various material surfaces. This design embodies high practicality and innovation, and is of great significance for improving existing technologies.

[0078] In one embodiment, the telescopic structure 30 in the above embodiments includes a spring.

[0079] In this embodiment, the spring is the core component of the telescopic structure 30. One end of the spring is fixed to the beater bar 10 or the bristles, while the other end can be fixed in different positions depending on the specific embodiment. For example, in embodiment two, the other end of the spring is fixed to a horizontal C-shaped fixing plate; while in embodiment three, it may be directly fixed inside a specially designed fixing housing 50.

[0080] Beating strips 10 / bristles: These components are responsible for actually contacting and beating the surface being cleaned. They are inserted into the placement slots 21 on the roller brush 20 and can extend and retract to a certain extent axially by the action of springs.

[0081] When the roller brush motor 91 starts and its speed increases, the tapping bar 10 attempts to move outward due to centrifugal force. At this time, the spring is compressed, allowing the tapping bar 10 to extend further into the placement groove 21, increasing the effective diameter of the roller brush. Conversely, when the roller brush motor 91 speed decreases or stops, the centrifugal force decreases, the spring returns to its original state, causing the tapping bar 10 to retract to its initial position or near its initial position.

[0082] When operating on hard surfaces, since the overall sinking amount is relatively small, the tapping force can be increased by increasing the speed of the roller brush motor 91. This results in greater centrifugal force, causing the spring to compress further and the tapping strip 10 to extend more, thus enhancing the tapping effect on the cleaning surface. For softer surfaces, the motor speed needs to be reduced to decrease the centrifugal force, allowing the spring to partially return to its original position and reducing the extension of the tapping strip 10 to avoid excessive pressure into the soft material and ensure appropriate tapping force.

[0083] The dust sensor monitors the dust concentration during operation and automatically adjusts the motor speed accordingly. When the dust concentration is high, the motor speed increases, driving the roller brush to rotate faster, increasing the spring compression, enlarging the roller brush diameter, and enhancing the beating force to achieve a better cleaning effect.

[0084] By utilizing the elastic properties of springs and combining them with an adjustable-speed motor, the tapping bar 10 can flexibly adjust its extension length according to different working conditions (such as surface hardness and dust volume), ensuring efficient cleaning performance in various environments. The springs not only provide necessary support and cushioning but also ensure the stability and reliability of the tapping bar 10 throughout its working cycle, reducing wear and tear caused by prolonged use.

[0085] In summary, the telescopic structure 30 provides an effective solution to the problem of non-adjustable brush diameter and beating force in traditional mite removers. By cleverly combining physical and mechanical principles with mechanical design, it achieves dynamic adjustment of the brush diameter and beating force, significantly improving the device's efficiency and effectiveness on various cleaning surfaces.

[0086] Specifically, the roller brush 20 is provided with multiple placement slots 21, which are arranged at intervals around the center of the roller brush 20, and each placement slot 21 is fitted with a tapping strip 10. Each tapping strip 10 is provided with multiple spaced telescopic structures 30 to ensure smooth telescopic movement.

[0087] As a key component of the mite remover, the roller brush 20's design directly affects the device's cleaning efficiency and effectiveness. Specifically, the roller brush 20 has multiple placement slots 21, which are spaced apart around the center of the roller brush 20. This layout not only ensures that the tapping strips 10 are evenly distributed around the roller brush 20, but also allows the roller brush to perform all-round, thorough tapping of the cleaning surface during rotation. Each placement slot 21 is used to insert one tapping strip 10. The advantage of this design is that the number and distribution of the tapping strips 10 can be flexibly adjusted according to different cleaning needs, improving the device's adaptability and flexibility. In addition, the presence of the placement slots 21 also provides installation space for the telescopic structure 30, ensuring that the tapping strips 10 can freely extend and retract within a certain range.

[0088] To ensure the smooth extension and retraction of the tapping strips 10 during operation, each tapping strip 10 is equipped with multiple spaced telescopic structures 30. These telescopic structures 30 are mainly composed of springs, which are evenly distributed at different positions of the tapping strips 10, effectively dispersing the pressure generated by centrifugal force. In this way, when the roller brush motor 91 drives the roller brush to rotate, the tapping strips 10 can smoothly extend or retract within the placement groove 21 as needed, thereby achieving dynamic adjustment of the roller brush diameter and tapping force. This design not only enhances the efficiency of the equipment on cleaning surfaces of different hardness but also significantly improves the consistency and stability of the cleaning effect. More importantly, it provides users with a simple and efficient method to handle diverse cleaning tasks without the need to change roller brushes of different specifications, greatly enhancing the user experience.

[0089] The aforementioned automatic telescopic tapping bar 10 integrates the tapping bar 10, the roller brush 20, and the telescopic structure 30 into one unit. The roller brush 20 has a placement groove 21, and one end of the tapping bar 10 is fitted into the groove, with the telescopic structure 30 also located in this groove to adjust the internal depth of the tapping bar 10. This achieves effective adaptation to cleaning surfaces of different hardness and improves performance. This design solves the problem of fixed and unadjustable roller brush diameter and tapping force in traditional mite removers, allowing flexible adjustment of tapping force according to cleaning needs. This overcomes the technical problem of inconsistent tapping effects on different surfaces due to the fixed extension of the tapping bar 10, greatly improving the cleaning efficiency and applicability of the mite remover in various environments.

[0090] In one embodiment, please refer to Figures 10 to 14The aforementioned cleaning equipment includes: a body assembly 60, a dust cup assembly 70, a roller brush cover assembly 80, and a roller brush assembly 90. The dust cup assembly 70 is located above the body assembly 60, the roller brush assembly 90 is located at the front end of both the body assembly 60 and the dust cup assembly 70, and the roller brush cover assembly 80 is located below the roller brush assembly 90. The roller brush cover assembly 80 and the body assembly 60 are combined to assemble the roller brush cavity. The roller brush assembly 90 includes a drive structure and the aforementioned automatic telescopic beater bar 10. The drive structure is connected to the roller brush bar 20. The body assembly 60 is provided with an air duct 61, and a dust sensor 100 is fixed in the air duct 61. The dust sensor 100 is used to sense the amount of dust in the air duct 61 during the operation of the whole machine, so as to adjust the rotation speed of the roller brush bar 20 through the dust sensor 100.

[0091] In this embodiment, the cleaning device, such as a mite remover, is structurally designed to improve cleaning efficiency and adapt to the cleaning needs of different surfaces. The device includes a body assembly 60, a dust cup assembly 70, a roller brush cover assembly 80, and a roller brush assembly 90, wherein:

[0092] The dust cup assembly 70 is located above the body assembly 60 and is used to collect dust and dust mites sucked from the cleaned surface.

[0093] The roller brush assembly 90 is located at the front end of the body assembly 60 and the front end of the dust cup assembly 70, ensuring that it contacts and treats the cleaning surface first during operation.

[0094] The roller brush cover assembly 80 is located below the roller brush assembly 90 and is assembled with the body assembly 60 to form the roller brush cavity, thus providing rotation space for the roller brush assembly 90.

[0095] In one embodiment, please refer to Figures 13 to 14 The aforementioned drive structure includes a roller brush motor 91, a motor bracket 92, a belt 93, a drive rod 94, and a bearing 95. The drive rod 94 is inserted into the roller brush rod 20, and a gear 96 is mounted on one end of the drive rod 94 through the bearing 95. The belt 93 is connected to the gear 96. The roller brush motor 91 is fixed on the motor bracket 92, and the roller brush motor 91 is connected to the gear 96 through the belt 93.

[0096] In this embodiment, the roller brush assembly 90 is unique in that it not only includes a traditional drive structure but also integrates an automatic telescopic tapping bar 10. This innovative design allows for adjustment of the tapping force and roller brush diameter according to different cleaning needs. Specifically, the drive structure includes components such as a roller brush motor 91, a motor bracket 92, a belt 93, a drive rod 94, and a bearing 95. The drive rod 94 is inserted into the roller brush bar 20, and a gear 96 is mounted on one end via the bearing 95. The belt 93 connects to this gear 96. The roller brush motor 91 is fixed on the motor bracket 92 and connected to the gear 96 via the belt 93, thereby driving the entire roller brush assembly 90 to rotate. Specifically, the roller brush motor 91 is connected to the gear 96 via the belt 93, and the gear 96 is fixed to the drive rod 94 and simultaneously fixed to the bearing 95 to achieve rotation. The roller brush bar 20 is mounted on the drive rod 94, thus enabling the roller brush motor 91 to rotate, thereby driving the rotation of the entire roller brush assembly 90.

[0097] In addition, the body assembly 60 is equipped with an air duct 61, in which a dust sensor 100 is fixed, enabling real-time monitoring of the amount of dust passing through the air duct 61 during machine operation. Based on the data provided by the dust sensor 100, the control system can dynamically adjust the rotation speed of the roller brush 20 to optimize the cleaning effect. When a high concentration of dust is detected, the system automatically increases the rotation speed of the roller brush motor 91, resulting in an increase in the roller brush diameter and thus enhancing the beating force to ensure optimal cleaning performance.

[0098] This design effectively solves the problems of fixed brush diameter and non-adjustable beating force in traditional mite removers, enabling the device to maintain a stable beating effect on cleaning surfaces of various hardness, significantly improving cleaning efficiency and user experience.

[0099] In this embodiment, the cleaning device aims to solve the problems of fixed roller brush diameter and non-adjustable patting force in the prior art. Through the coordinated work of a series of mechanical and electronic components, it achieves the function of maintaining a stable patting effect on cleaning surfaces of different hardness.

[0100] When the machine is running, the roller brush motor 91 starts. This motor is an adjustable-speed motor, such as a DC motor. The motor drives the roller brush assembly 90 to rotate via belt 93, thereby achieving the cleaning function. The mite remover has multiple adjustable speed settings, allowing users to select the appropriate setting for different cleaning surfaces.

[0101] When cleaning hard surfaces (such as wood floors or tiles), where the overall sinking is less, users can choose to adjust the speed to a high-speed mode. In this mode, the rotational speed of the roller brush motor 91 increases, causing the roller brush assembly 90 to rotate faster. As the roller brush speed increases, the tapping strip 10 experiences greater centrifugal force in the placement groove 21, compressing the spring and causing the tapping strip 10 to extend further outward. This increased extension directly results in a larger effective diameter of the entire roller brush, and a greater portion of the tapping strip 10 extends beyond the roller brush cover, thereby enhancing the tapping force on the cleaning surface and improving the tapping effect.

[0102] For softer surfaces (such as carpets), where the entire machine sinks more, the user can reduce the speed of the roller brush motor 91. Lower speed means less centrifugal force, allowing the spring to return to its original position and the beater bar 10 to retract, reducing the effective diameter of the roller brush and preventing excessive damage to soft materials. This adjustment mechanism ensures ideal cleaning results on surfaces of varying hardness.

[0103] Furthermore, the system supports fully automatic sensor-based adjustment. The dust sensor detects the dust concentration in the environment and identifies different cleaning surfaces based on different sensor types (such as pressure sensors and far-infrared sensors). Once the dust sensor detects a high dust concentration, it transmits the data to the controller's control unit. The control unit analyzes this data to determine the current dust concentration level. If a high dust concentration is detected, the control unit sends a signal to the motor driver, causing the motor driver to increase the motor speed. As the motor speed increases, the roller brush speed also increases, the roller brush diameter becomes larger, and the beating force is enhanced, thereby improving the beating effect.

[0104] Users can flexibly select different speed settings to adjust the rotation speed of the roller brush motor 91 according to the different surfaces being cleaned, ensuring optimal cleaning results. Ideal results can be achieved on both hard floors and soft carpets. A dust sensor monitors dust concentration in real time and automatically adjusts the motor speed, ensuring efficient cleaning even in high-dust environments. The device automatically responds optimally to actual conditions, eliminating the need for frequent manual adjustments, greatly simplifying the operation process and improving ease of use and comfort. A spring system adjusts the extension of the beater bar 10, ensuring structural stability and reliability, extending service life, and reducing maintenance costs. In addition to basic beating and vacuuming functions, different sensors can be used to identify various cleaning environments, enhancing the product's versatility. For example, pressure sensors or far-infrared sensors can be used to distinguish different types of surface materials, further optimizing cleaning strategies.

[0105] In summary, this device, by integrating advanced mechanical and electronic components, provides a more intelligent, efficient, and easy-to-use solution, significantly improving the challenges faced by traditional mite removers when cleaning surfaces of different materials.

[0106] The cleaning device of this embodiment achieves performance optimization and surface adaptability in different environments by integrating an automatic retractable beater bar 10. Specifically, the device includes an adjustable-speed drive structure and an automatic retractable beater bar 10 with a spring mechanism, allowing the beater bar 10 to automatically adjust its extension according to changes in centrifugal force, thereby changing the effective diameter of the roller brush and the beating force. When the device operates on a hard surface, the high speed results in greater centrifugal force, causing the beater bar 10 to extend further and increase the beating effect; conversely, on a soft surface, the low speed reduces centrifugal force, allowing the beater bar 10 to retract to avoid over-beating. In addition, the dust sensor 100 on the body assembly 60 can monitor the dust concentration in real time and automatically adjust the roller brush speed accordingly, further improving cleaning efficiency. This design effectively solves the problem of fixed and non-adjustable roller brush diameter and beating force in traditional mite removers, ensuring optimal cleaning results on surfaces of varying hardness.
