Description

Technical Field

[0001] This utility model relates to the field of mite removal technology, specifically to a cleaning roller and a mite removal device. Background Technology

[0002] Currently, most mite removers on the market suffer from the problem of pulling and stretching bedding during use, especially when cleaning soft, thin fabrics. Existing mite removers typically use a single suction port combined with a tapping device for mite removal. Their suction range is fixed, easily drawing bedding into the suction port, causing fabric stretching and deformation, and affecting the user experience. Furthermore, users need to frequently adjust the angle or intensity of the mite remover during operation, increasing the complexity of use. Therefore, how to effectively prevent the stretching and stretching of bedding during use while ensuring mite removal effectiveness has become an urgent problem to be solved. Utility Model Content

[0003] In view of this, the present invention provides a cleaning roller and a mite remover to solve the problem that the mite remover easily attracts bedding and causes pulling during use.

[0004] In a first aspect, this utility model provides a cleaning roller, comprising: The first air duct is equipped with an intake port; The roller body is rotatably fitted around the periphery of the first air duct; multiple air inlets are distributed on the circumferential surface of the roller body; during the rotation of the roller body relative to the first air duct, the air inlets can periodically communicate with the suction port.

[0005] Beneficial effects: During the rotation of the drum body, the air inlet holes on it periodically connect with the suction port of the first air duct. When the air inlet holes and the suction port are connected, the negative pressure in the first air duct acts on the bedding on the working surface. As the drum body continues to rotate, the connection area between the air inlet holes and the suction port gradually shrinks until the two are no longer connected. At this time, the suction no longer acts on the bedding. The periodic connection between the air inlet holes and the suction port makes the adsorption of the bedding also change periodically, thereby avoiding the pulling problem caused by continuous adsorption. It saves users more effort, and the bedding is less likely to be pulled into the drum body, improving the ease of operation and safety of using the mite remover.

[0006] In one alternative embodiment, at least two of the plurality of air inlets are spaced apart circumferentially along the roller body.

[0007] Beneficial effects: At least two air inlets spaced circumferentially around the roller increases the frequency of adsorption (connection) and desorption (disconnection) cycles during one rotation. This higher frequency allows the bedding surface to undergo more alternating adsorption and release cycles per unit time, effectively providing a more intensive pulsed action. This high-frequency dynamic change reduces localized stretching and deformation caused by single continuous adsorption, while repeated release actions reduce the risk of excessive fiber stretching, further alleviating operational resistance caused by continuous adsorption. High-frequency circulation means more even negative pressure on the bedding. Even with a constant roller rotation speed, multiple spaced air inlets allow negative pressure to alternate more frequently at different locations, reducing blind spots caused by the limited adsorption range of a single air inlet and enhancing the disturbance and adsorption effect on deep-seated dust mites and dander. Because the periodic changes in adsorption force are more frequent, the instantaneous pulling force on the bedding is more dispersed, resulting in smoother resistance fluctuations when the user pushes the mite remover, avoiding the stuttering or dragging sensation caused by single continuous adsorption, making operation smoother and less strenuous. At the same time, high-frequency adsorption and desorption can release fibers that may become entangled in time, reducing the risk of bedding being rolled into the roller and improving safety.

[0008] In one alternative embodiment, the plurality of air inlets are evenly distributed on the circumferential surface of the roller body.

[0009] Beneficial effects: Evenly distributed air intakes mean that when the roller rotates, negative pressure evenly covers every area of ​​the bedding surface, avoiding the problem of localized over-adsorption and sluggish adsorption caused by single or unevenly distributed pores. This ensures that different areas of the bedding receive the same intensity of negative pressure, thoroughly removing dust mites and dander. The evenly distributed air intakes allow the roller to complete one connection and disconnection cycle every fixed rotation angle, resulting in a stable and consistent cycle frequency. The adsorption force on the bedding changes evenly, without sudden strong or weak fluctuations. This makes the user's hand movement smoother, without any jamming or dragging sensation. The evenly distributed design also makes the connection and disconnection rhythm between the air intakes and the first air duct inlet more regular during the roller's rotation, preventing wasted or insufficient negative pressure due to uneven pore distribution. The more evenly distributed negative pressure agitates the bedding per unit time, more efficiently removing deep-seated dust mites and debris, resulting in a more stable cleaning effect than unevenly distributed designs.

[0010] In one alternative embodiment, the first air duct is cylindrical, and the intake port is formed on the circumferential surface of the first air duct along its axial direction.

[0011] Beneficial effects: The axial intake of the cylindrical air duct forms a long, strip-shaped negative pressure adsorption band parallel to the axis of the drum body. This band can cover the entire axial length of the drum body in one go, eliminating the need for the drum body to rotate to compensate for axial adsorption gaps. Even if the axial dimension of the drum body is long, it ensures consistent adsorption strength at both ends and the middle area, avoiding the hidden problem of weak adsorption at both ends of the axis. The long strip design of the intake increases the air intake cross-sectional area, and the airflow can enter the first air duct without turning.

[0012] In one alternative implementation, the circumferential width of the air inlet matches the circumferential width of the intake port.

[0013] Beneficial effects: When the circumferential widths of the two components are matched, a full-width, close-fitting airflow channel is formed instantly upon connection between the air inlet and the inlet. This avoids negative pressure throttling caused by an excessively narrow air inlet or airflow congestion caused by an excessively narrow inlet, ensuring that negative pressure can fully act on the bedding through the air inlet. Width matching optimizes the ratio between the effective adsorption time during the connection phase and the release time during the disconnection phase.

[0014] In one optional embodiment, the cleaning roller further includes: The slapping roller brush is detachably installed inside the first air duct.

[0015] Beneficial effects: The beating roller brush is built into the first air duct, forming a close-range collaborative working mode. The dust mites and dander generated when the roller brush beats the bedding will fall directly into the negative pressure field in the air duct, without having to go through long-distance transmission of beating-scattering-adsorption, reducing dust escape. In particular, it can efficiently capture the tiny debris that is beaten up, improving the mite removal effect.

[0016] In one optional implementation, the tapping roller brush includes: The driving component is located in the first air duct; A transmission assembly is disposed in the first air duct, and the transmission assembly is connected to the drive component; The brush body has its first end connected to the drive component via the transmission assembly, and its second end abutting against the first air duct via a bushing.

[0017] Beneficial effects: The first end of the roller brush body is rigidly driven by the transmission component, and the second end is abutted against the first air duct by the bushing, forming a support structure with one end driving and the other end positioning. This not only ensures the accuracy of power transmission, but also reduces the precision requirements for synchronous assembly at both ends.

[0018] In one optional embodiment, the bushing is provided with an elastic deformation portion, and the brush body abuts against the first air duct through the elastic deformation portion.

[0019] Beneficial effects: The elastic deformation section can adaptively expand or deform according to assembly deviations (such as minor errors in shaft length or roundness deviations in the inner wall of the air duct), eliminating the gap between the second end of the roller brush body and the inner wall of the first air duct without the need for high-precision control of part dimensions. This prevents axial movement or radial swaying during the rotation of the roller brush body, resulting in more precise tapping action. It overcomes the dilemma of traditional rigid bushings that are either too tight and jamming or too loose and wobbling, significantly improving assembly error tolerance and reducing manufacturing costs.

[0020] In one alternative embodiment, the roller brush body includes a slapping rubber strip and a slapping bristle strip, the slapping rubber strip and the slapping bristle strip being alternately disposed on the rotating shaft of the roller brush body.

[0021] Beneficial effects: The high-hardness of the tapping rubber strip creates a rigid impact, powerfully tapping deep into the bedding to disperse hidden dust mites, insect eggs, and clumps of dander. Meanwhile, the soft tapping bristles provide a gentle sweep, combing along the bedding fibers to collect surface dust and tiny debris dislodged by the rubber strips, preventing dust residue or escape. The alternating action of the two is equivalent to shaking followed by sweeping; a single rotation completes both deep cleaning and surface removal, resulting in better cleaning efficiency than either a single rubber strip or bristles. The alternating arrangement of the rubber and bristles creates a natural gap-like layout, preventing complete blockage of airflow around the roller brush during tapping, allowing negative pressure to smoothly pass through the gaps and act on the bedding surface. During the combing process, the bristles guide dust into the airflow channels, and the dust generated by the impact of the rubber strips is quickly sucked away by the negative pressure through the gaps, reducing secondary dust diffusion and enhancing the synergistic adsorption effect.

[0022] In one alternative embodiment, a friction structure is provided on the rolling surface of the roller body.

[0023] Beneficial effects: The friction structure increases the friction between the roller and the bedding surface, breaking the traditional passive following and pushing mode of smooth rollers. When the roller rotates, the friction structure generates a forward traction force, causing the mite remover to actively conform to the bedding and feed. Users do not need to push it with extra force, especially in scenarios with high resistance such as thick bedding and mattresses, making operation more effortless and avoiding problems such as not being able to push it or slipping. Moreover, the presence of friction makes the roller roll more smoothly, preventing it from jumping due to the texture of the bedding surface, ensuring that the adsorption, patting actions and rolling rhythm are precisely matched.

[0024] Secondly, this utility model also provides a mite removal device, comprising: Organism; The cleaning roller described in any of the above embodiments is mounted on the machine body.

[0025] Beneficial effects: Since the mite remover includes the cleaning roller of this utility model, it has the same technical effects as the cleaning roller, which will not be described in detail here.

[0026] In one alternative embodiment, the body includes: The outer casing, on which the cleaning roller is mounted; the outer casing is provided with vent holes; The dust cup is connected to the exhaust port; The second air duct is connected between the dust cup and the first air duct.

[0027] Beneficial effects: The second air duct connects the first air duct and the dust cup, and together with the exhaust vent on the outer casing, it forms a complete negative pressure closed loop: the first air duct adsorption, the second air duct transmission, the dust cup dust collection, and the exhaust vent exhaust. The airflow path is continuous and without redundant turns, avoiding leakage or loss of negative pressure during transmission, ensuring that the adsorption force of the first air duct can be stably transmitted, and improving the delivery efficiency of dust mites and dander.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] The following is combined Figures 1 to 16 The following describes embodiments of the present invention.

[0035] According to an embodiment of the present invention, a cleaning roller 100 is provided, comprising: The first air duct 102 is equipped with an intake 1021; The roller body 101 is rotatably sleeved around the first air duct 102; a plurality of air inlets 1011 are distributed on the circumferential surface of the roller body 101; during the rotation of the roller body 101 relative to the first air duct 102, the air inlets 1011 can periodically communicate with the suction port 1021.

[0036] During the rotation of the roller body 101, the air inlet 1011 on it periodically connects with the suction port 1021 of the first air duct 102. When the air inlet 1011 and the suction port 1021 are connected, the negative pressure in the first air duct 102 acts on the bedding on the working surface. As the roller body continues to rotate, the connection area between the air inlet 1011 and the suction port 1021 gradually shrinks until the two are no longer connected. At this time, the suction no longer acts on the bedding. The periodic connection between the air inlet 1011 and the suction port 1021 makes the adsorption of the bedding also change periodically, thereby avoiding the pulling problem caused by continuous adsorption. It saves the user effort, and the bedding is less likely to be rolled into the roller body 101, improving the ease of operation and safety of the mite remover during use.

[0037] In some embodiments, at least two of the plurality of air inlets 1011 are arranged at circumferential intervals along the roller body 101.

[0038] At least two air inlets 1011 are spaced circumferentially along the roller body 101, increasing the frequency of adsorption (connection) and desorption (disconnection) cycles during one rotation of the roller body 101. A higher cycle frequency allows the bedding surface to undergo more alternating adsorption and release cycles per unit time, equivalent to a more intensive pulsed action on the bedding. This high-frequency dynamic change reduces localized stretching and deformation of the bedding caused by single continuous adsorption, while repeated release actions reduce the risk of excessive stretching of bedding fibers, further alleviating operational resistance caused by continuous adsorption. High-frequency circulation means more even negative pressure on the bedding. Even with a constant roller rotation speed, multiple spaced air inlets 1011 allow negative pressure to alternate more frequently at different locations, reducing cleaning blind spots caused by the limited adsorption range of a single air inlet 1011, and enhancing the disturbance and adsorption effect on deep-seated dust mites and dander in the bedding. Because the adsorption force changes more frequently and the instantaneous pulling force on the bedding is more dispersed, the resistance fluctuations felt by the user when pushing the mite remover are smoother, avoiding the stuttering or dragging sensation caused by continuous single adsorption, making operation smoother and less strenuous. At the same time, the high-frequency adsorption and desorption can release any fibers that may become entangled in time, reducing the risk of bedding being pulled into the drum and improving safety during use.

[0039] In some embodiments, a plurality of air inlets 1011 are evenly distributed on the circumferential surface of the roller body 101.

[0040] The evenly distributed air inlets 1011 mean that when the roller body 101 rotates, the negative pressure can evenly cover every area of ​​the bedding surface, avoiding the problem of localized excessive adsorption and some areas lacking adsorption caused by single or unevenly distributed holes. This ensures that different parts of the bedding receive the same intensity of negative pressure, thoroughly removing dust mites and dander. The evenly distributed air inlets 1011 allow the roller body 101 to complete one connection and disconnection cycle every fixed angle of rotation. The cycle frequency is stable and the intervals are consistent, resulting in uniform changes in the adsorption force on the bedding, without drastic fluctuations such as sudden strong suction and sudden lack of suction. This makes the user feel smoother when pushing the mite remover, without any jamming or dragging sensation. The evenly distributed design also makes the connection and disconnection rhythm of the air inlets 1011 and the suction inlet 1021 of the first air duct 102 more regular during the rotation of the roller body 101, preventing waste or insufficiency of negative pressure due to uneven hole distribution. The negative pressure agitates the bedding more evenly per unit time, which can more efficiently remove deep-seated dust mites and debris, resulting in a more stable cleaning effect than a non-uniform design.

[0041] In some embodiments, the first air duct 102 is cylindrical, and the intake port 1021 is formed on the circumferential surface of the first air duct 102 along the axial direction of the first air duct 102.

[0042] The axial intake 1021 of the cylindrical air duct forms a long, strip-shaped negative pressure adsorption band parallel to the axis of the drum body 101. This band can cover the entire axial length of the drum body 101 in one go, eliminating the need for rotation of the drum body 101 to compensate for axial adsorption gaps. Even if the axial dimension of the drum body 101 is long, it ensures consistent adsorption strength at both ends and the middle area, avoiding the hidden problem of weak adsorption at both ends of the axis. The long strip design of the intake 1021 increases the air intake cross-sectional area, and the airflow can enter the first air duct 102 without turning.

[0043] In some embodiments, the circumferential width of the air inlet 1011 matches the circumferential width of the intake port 1021.

[0044] When the circumferential widths of the two are matched, a full-width, fitted airflow channel is formed instantly upon connection between the air inlet 1011 and the inlet 1021. This avoids negative pressure throttling caused by an excessively narrow air inlet 1011 or airflow congestion caused by an excessively narrow inlet 1021, ensuring that negative pressure can fully act on the bedding through the air inlet 1011. This width matching optimizes the ratio between the effective adsorption time during the connection phase and the release time during the disconnection phase.

[0045] In some embodiments, the cleaning roller 100 further includes: The slapping roller brush 103 is detachably installed inside the first air duct 102.

[0046] The beating roller brush 103 is built into the first air duct 102, forming a close-range collaborative working mode. When the roller brush beats the bedding, the dust mites and dander generated will fall directly into the negative pressure field in the air duct, without having to go through long-distance transmission of beating-scattering-adsorption, reducing dust escape. In particular, it can efficiently capture the tiny debris that is beaten up, improving the mite removal effect.

[0047] In some embodiments, the slapping roller brush 103 includes: The driving component is disposed in the first air duct 102; A transmission assembly is disposed in the first air duct 102, and the transmission assembly is connected to the driving component; The roller brush body has its first end connected to the drive component via the transmission assembly, and its second end abutting against the first air duct 102 via a bushing 1033.

[0048] The first end of the roller brush body is rigidly driven by a transmission component, and the second end abuts against the first air duct 102 through a bushing 1033, forming a support structure with one end driving and the other end positioning. This not only ensures the accuracy of power transmission, but also reduces the precision requirements for synchronous assembly at both ends.

[0049] Specifically, the driving component can be a drive motor, and the transmission component can be a belt drive mechanism.

[0050] In some embodiments, the bushing 1033 is provided with an elastic deformation portion 10331, and the roller brush body abuts against the first air duct 102 through the elastic deformation portion 10331.

[0051] The elastic deformation section 10331 can adaptively expand, contract, or deform according to assembly deviations (such as minor errors in shaft length or roundness deviations in the inner wall of the air duct). This eliminates the gap between the second end of the roller brush body and the inner wall of the first air duct 102 without requiring high-precision control of part dimensions, preventing axial movement or radial swaying during roller brush rotation and resulting in more precise striking action. It overcomes the dilemma of traditional rigid bushings 1033 being either too tight and jamming or too loose and wobbling, significantly improving assembly tolerance and reducing manufacturing costs.

[0052] In some embodiments, the roller brush body includes a tapping rubber strip 1031 and a tapping bristle strip 1032, the tapping rubber strip 1031 and the tapping bristle strip 1032 being alternately disposed on the rotating shaft of the roller brush body.

[0053] The 1031 tapping strip is relatively hard, creating a rigid impact that powerfully taps deep into the bedding, dispersing hidden dust mites, insect eggs, and clumps of dander. The 1032 tapping brush, on the other hand, is soft and provides gentle cleaning, combing along the bedding fibers to collect surface dust and tiny debris dislodged by the strip, preventing dust residue or escape. The alternating action of the two is equivalent to a combination of vibration and sweeping, completing both deep cleaning and surface removal in a single rotation, resulting in better cleaning efficiency than either a single strip or brush alone. The alternating arrangement of the 1031 and 1032 tapping strips creates a natural gap-like layout, preventing complete blockage of airflow around the roller brush during tapping, allowing negative pressure to smoothly pass through the gaps and act on the bedding surface. During the combing process, the 1032 tapping brush guides dust into the airflow channels, while the dust generated by the impact of the 1031 tapping strip is quickly sucked away by the negative pressure through the gaps, reducing secondary dust diffusion and enhancing the synergistic adsorption effect.

[0054] In some embodiments, a friction structure is provided on the rolling surface of the roller body 101.

[0055] The friction structure increases the friction between the roller and the bedding surface, breaking away from the traditional passive following and pushing mode of a smooth roller. When the roller body 101 rotates, the friction structure generates a forward traction force, causing the mite remover to actively conform to the bedding and feed. Users do not need to push it with extra force, which is especially helpful in scenarios with high resistance such as thick bedding and mattresses, making operation more effortless and avoiding problems such as not being able to push it or slipping off course. Moreover, the presence of friction makes the roller roll more smoothly and will not jump due to the texture of the bedding surface, ensuring that the adsorption, patting action and rolling rhythm are precisely matched.

[0056] According to an embodiment of the present invention, another aspect provides a mite removal device, comprising: Organism; Cleaning roller 100 is mounted on the machine body.

[0057] Since the mite removal device includes the cleaning roller 100 of this utility model, it has the same technical effects as the cleaning roller 100, which will not be described in detail here.

[0058] In some embodiments, the body includes: The outer casing 200 is provided with the cleaning roller 100 mounted on it; the outer casing 200 is provided with an exhaust hole 201. Dust cup 300 is connected to the exhaust port 201; The second air duct 400 is connected and disposed between the dust cup 300 and the first air duct 102.

[0059] The second air duct 400 connects the first air duct 102 and the dust cup 300. Together with the exhaust port 201 on the outer casing 200, it forms a complete negative pressure closed loop: the first air duct 102 adsorbs dust, the second air duct 400 transports it, the dust cup 300 collects dust, and the exhaust port 201 exhausts the air. The airflow path is continuous and without redundant turns, preventing leakage or loss of negative pressure during transmission, ensuring stable transmission of the adsorption force of the first air duct 102, and improving the efficiency of transporting dust mites and dander.

[0060] This utility model provides a mite remover with a periodic adsorption function, including a body and a cleaning roller 100. The body contains a power component for generating negative pressure. The cleaning roller 100 has a first air duct 102 with an intake 1021 located at the bottom of the body for contacting the surface to be cleaned. The cleaning roller 100 includes a roller body 101 rotatably mounted outside the intake 1021. The roller body 101 has multiple air inlets 1011 circumferentially distributed on its surface.

[0061] During use, when the user pushes the mite remover forward or backward, the roller body 101 rolls while in contact with the bedding surface. Because the roller body 101 has multiple air inlets 1011, as the roller body 101 rolls, the air inlets 1011 periodically align with the suction inlet 1021, thus forming a localized adsorption area. When the air inlets 1011 and suction inlet 1021 are misaligned, the adsorption in that area is released, achieving a periodic adsorption effect. This periodic adsorption and desorption effectively solves the problem of the mite remover pulling on the fabric, preventing fabric deformation, and improving the user experience.

[0062] Figure 1 An isometric view of the mite remover is provided. Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This is a diagram illustrating the working principle of a mite remover, such as... Figure 4 and Figure 5 As shown, the quilt 600 will sink into the air inlet 1011 of the roller body 101 so that the patting brush 103 can pat the quilt 600. Figure 2 As shown, under the action of the power component, the power component generates negative pressure, which will draw the dust mites knocked down by the beating roller brush 103 through the first air duct 102 and then through the second air duct 400 into the dust cup 300. In the dust cup 300, the dust mites are separated from the air. The dust mites remain in the dust cup 300, while the air is discharged through the exhaust port 201 on the side of the outer casing 200.

[0063] like Figure 4 and Figure 5As shown, the roller body 101 is provided with five air inlets 1011 at intervals around its circumference, namely the first air inlet 1011-1, the second air inlet 1011-2, the third air inlet 1011-3, the fourth air inlet 1011-4 and the fifth air inlet 1011-5. When the suction port 1021 of the first air duct 102 aligns with the first air inlet 1011-1 of the drum body 101, the first air inlet 1011-1 of the drum body 101 has suction and will attract the quilt 600. When the mite remover is pushed forward, the drum body 101 rotates, and the first air inlet 1011-1 on the drum body 101 is no longer aligned with the suction port 1021 of the first air duct 102. At this time, the first air inlet 1011-1 of the drum body 101 has no suction and no longer attracts the quilt 600. Therefore, when the mite remover is pushed forward, the quilt 600 will fall off from the first air inlet 1011-1 of the drum. At this time, the second air inlet 1011-2 on the drum body 101 is aligned with the suction port 1021 of the first air duct 102 (e.g., ...). Figure 5 As shown), at this time, the second air inlet 1011-2 of the roller body 101 will adsorb the quilt 600. This cycle is repeated to form a mite remover that does not pull the quilt 600.

[0064] like Figure 6 As shown, the first air duct 102 is fixed to the outer casing 200 by structural design. The first air duct 102 is stationary relative to the outer casing 200, while the roller body 101 is rotatable relative to the outer casing 200 and the first air duct 102. When the mite remover is pushed forward or pulled backward, the roller body 101 rolls forward or backward. Figure 11 The installation structure diagram of the second air duct 400 is given, combined with... Figure 7 and Figure 11 It can be seen that the second air duct 400 is a channel connecting the first air duct 102 and the dust cup 300, and the second air duct 400 is fixed to the outer casing 200 and the first air duct 102 by screws. Figure 12 As shown, the first air duct 102 is fixed to the housing 200 by screws. Figure 13 As shown, the roller body 101 is fitted onto the first air duct 102 with a gap. Both ends of the roller body 101 are fitted onto both ends of the outer shell 200, with gaps left at each fitting position, so that the roller body 101 can rotate relative to the outer shell 200 and the first air duct 102.

[0065] like Figure 14 As shown, roller bearings 700 can also be added between the two ends of the roller body 101 and the outer shell 200 to make the rolling of the roller body 101 smoother.

[0066] like Figure 7As shown, the airflow enters the first air duct 102 through the air inlet of the drum body 101, then enters the dust cup 300 through the second air duct 400. After being separated by the dust cup 300, the airflow enters the vacuum motor and finally exits through the exhaust port 201 on the right cover of the outer casing 200.

[0067] like Figure 9 As shown, the roller brush body is provided with two rows of slapping rubber strips 1031 and two rows of slapping bristle strips 1032.

[0068] Figure 10 This is an installation structure diagram of the roller brush body. One end of the roller brush is assembled with a bearing and a bushing 1033, and then together they are assembled to abut against the first air duct 102. The other end of the roller brush body is assembled to the transmission rod 1034 of the transmission assembly fixed to the first air duct 102. The transmission rod 1034, together with the bearing and the transmission gear 1035, is assembled and fixed to the first air duct 102. Figure 12 As shown, the roller brush motor drives the transmission gear 1035 via the transmission belt 1036, which in turn drives the roller brush body to rotate. The bushing 1033 has an elastic deformation part 10331, which can prevent the roller brush body from moving left and right.

[0069] This invention features a cleaning roller 100 located outside the suction inlet 1021 of the first air duct 102, in addition to the beating brush 103. The roller body 101 has multiple air inlets 1011, allowing the quilt 600 to be inserted into these inlets and patted by the beating brush 103. As the roller rotates, its air inlets 1011 periodically align with the suction inlet 1021 of the first air duct 102, creating a cyclical adsorption and desorption process between the roller body 101 and the quilt 600, thus preventing the quilt 600 from being pulled.

[0070] like Figure 3 As shown, a sealing strip 500 can be designed around the intake 1021 of the first air duct 102 to reduce negative pressure loss and enhance the mite removal effect. The sealing strip 500 and the first air duct 102 are integrally formed by double injection molding.

[0071] Raised ribs are provided on the outer periphery of the roller body 101, which can generate greater friction between the roller and the quilt 600, so that the roller body 101 rolls rather than slides when the mite remover is pushed and pulled. The raised ribs on the outer periphery of the roller body 101 can be made of soft rubber and are integrated with the roller body 101 by double injection molding.

[0072] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
