Abstract
Description
Technical Field
[0001] The utility model relates to the field of cleaning equipment, in particular to a roller brush mechanism and a cleaning equipment. Background Art
[0002] With the continuous improvement of people's living standards, people's requirements for the living environment are also getting higher and higher. The application of cleaning equipment is becoming more and more extensive, and it has a very broad market prospect.
[0003] Existing cleaning equipment such as vacuum cleaners usually includes a roller brush to improve the cleaning effect. However, during the cleaning process, the roller brush is relatively easy to entangle with hair. When a large amount of hair is entangled on the roller brush, the user needs to maintain and clean the roller brush. In the prior art, a cutter is usually equipped, and the user uses the cutter to cut and clean the hair entangled on the roller brush. However, the above process is very troublesome and cumbersome, resulting in poor user experience. Summary of the Utility Model
[0004] In order to overcome the deficiencies in the prior art, the utility model provides a roller brush mechanism, which can disassemble the roller brush from the roller brush receiving cavity to facilitate the user to clean and maintain the roller brush. And by rotating the roller brush mounting side plate, the roller brush assembly and the basic mechanism can be unlocked and locked. The user can very conveniently disassemble and assemble the roller brush assembly and the basic component, which is convenient for the user to use. The present utility model also provides a cleaning equipment.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions to implement:
[0006] A roller brush mechanism is provided on a cleaning equipment capable of traveling on an operation surface, including:
[0007] A basic component, the basic component is provided with a roller brush receiving cavity, the roller brush receiving cavity is configured to extend along a direction perpendicular to the traveling direction of the cleaning equipment, and the extending direction of the roller brush is parallel to the operation surface. The two ends of the roller brush receiving cavity in its extending direction are respectively formed as a first roller brush receiving cavity end and a second roller brush receiving cavity end. The first roller brush receiving cavity end extends toward the side away from the second roller brush receiving cavity end and penetrates through the basic component to form a roller brush disassembly and assembly opening;
[0008] A roller brush assembly, the roller brush assembly includes a roller brush and a roller brush mounting side plate. The roller brush rotation connection end of the roller brush is rotationally connected to the roller brush mounting side plate, and the other end is formed as a roller brush free end;
[0009] The brush roller mounting side plate is configured to be able to drive the brush roller into the brush roller receiving cavity until the brush roller mounting side plate moves to the brush roller disassembly and assembly opening; and the brush roller mounting side plate can rotate relative to the brush roller disassembly and assembly opening to achieve locking and unlocking between the two.
[0010] It should be noted that when the brush roller mounting side plate and the brush roller disassembly and assembly opening are locked, the brush roller mounting side plate is restricted from moving relative to the brush roller disassembly and assembly opening in the brush roller disassembly and assembly direction.
[0011] In use, the brush roller mechanism is arranged on the cleaning device. When the cleaning device moves forward, the rotating brush roller can clean the operation surface. Specifically, the brush roller receiving cavity is a lower-opening cavity; the operation surface is usually the ground.
[0012] With the above structure, the user can conveniently disassemble the brush roller assembly from the basic component or install the brush roller assembly onto the basic component, which is convenient for the user to clean and maintain the brush roller daily. For example, when a large amount of hair is wound around the brush roller and needs to be cleaned;
[0013] Specifically, when disassembly is required, the user only needs to operate the brush roller mounting side plate to rotate it relative to the brush roller disassembly and assembly opening to unlock it from the brush roller disassembly and assembly opening. At this time, the user can pull out the brush roller assembly from the brush roller disassembly and assembly opening, and then the user can clean the brush roller;
[0014] When installation is required, the user only needs to align the free end of the brush roller of the brush roller with the brush roller disassembly and assembly opening, and then insert the brush roller into the brush roller receiving cavity through the brush roller disassembly and assembly opening until the brush roller mounting side plate moves to the brush roller disassembly and assembly opening; the user only needs to rotate the brush roller mounting side plate to lock it with the brush roller disassembly and assembly opening. At this time, the brush roller assembly is installed onto the basic component;
[0015] The above structure is convenient to operate, greatly improving the user experience.
[0016] Further, the brush roller mounting side plate is provided with a first installation locking structure. Correspondingly, the brush roller disassembly and assembly opening is provided with a second installation locking structure that matches the first installation locking structure;
[0017] During the rotation of the brush roller mounting side plate relative to the brush roller disassembly and assembly opening, there are a locking working position and an unlocking working position. And the first installation locking structure and the second installation locking structure are configured to lock when the brush roller mounting side plate rotates to the locking position and unlock when the brush roller mounting side plate rotates to the unlocking position.
[0018] With the above structure, the first installation locking structure and the second installation locking structure are arranged such that when the roller brush installation side plate rotates relative to the roller brush disassembly and assembly opening, unlocking and locking with the roller brush disassembly and assembly opening can be achieved; the structural design is reasonable.
[0019] Further, when the roller brush installation side plate moves to the position of the roller brush disassembly and assembly opening, the locking and cooperating side wall of the roller brush installation side plate is arranged opposite to the locking and cooperating inner wall of the roller brush disassembly and assembly opening;
[0020] The first installation locking structure includes a first limiting block and a second limiting block arranged on the locking and cooperating side wall. The first limiting block and the second limiting block are spaced apart in the roller brush disassembly and assembly direction, and when the roller brush installation side plate enters the roller brush disassembly and assembly opening, the first limiting block enters the roller brush disassembly and assembly opening prior to the second limiting block;
[0021] The second installation locking structure includes a third limiting block and a limiting inlet and outlet arranged on the locking and cooperating inner wall. The third limiting block and the limiting inlet and outlet are distributed along the rotation direction of the roller brush installation side plate;
[0022] In the roller brush installation direction, both end faces of the third limiting block are respectively formed as a first limiting surface and a second limiting surface, and the distance between the first limiting surface and the second limiting surface is not greater than the interval distance between the first limiting block and the second limiting block; in the rotation direction of the roller brush installation side plate, the width of the limiting inlet and outlet matches the width of the first limiting block so that the first limiting block can move through and move to the side of the second limiting surface away from the first limiting surface.
[0023] In the roller brush installation direction, both end faces of the third limiting block are respectively formed as a first limiting surface and a second limiting surface, which can be understood as: when the roller brush installation extends into the roller brush receiving cavity, the first limiting block will first pass through the first limiting surface and then pass through the second limiting surface.
[0024] With the above structure, during installation, the user needs to align the first limiting block with the selected limiting inlet and outlet. When the roller brush installation side plate moves to the roller brush disassembly and assembly opening, the first limiting block will pass through the limiting inlet and outlet and move to the side of the second limiting surface of the third limiting block. The user then needs to rotate the roller brush installation side plate so that the first limiting block is opposite to the second limiting surface of the third limiting block. At this time, the third limiting block is located between the first limiting block and the second limiting block, thereby restricting the movement of the roller brush installation side plate relative to the roller brush disassembly and assembly opening in the roller brush disassembly and assembly direction. The locking between the roller brush installation side plate and the roller brush disassembly and assembly opening is achieved;
[0025] When disassembling, the user needs to rotate the roller brush mounting side plate so that the first limiting block moves from being opposite to the third limiting block to being opposite to the limiting inlet and outlet. At this time, the restriction of the first limiting block and the second limiting block on the third limiting block is released, and at this time, the user can pull out the roller brush group from the basic component; the above structure is reasonably designed.
[0026] Further, along the direction in which the roller brush mounting side plate rotates from the unlocking working position to the locking working position, the two ends of the first limiting block are respectively formed as a first limiting end and a second limiting end, and at least one side of the side wall of the second limiting end facing the second limiting block is configured as a limiting guiding surface, and the limiting guiding surface is used to guide the first limiting block to move to be opposite to the side of the second limiting surface away from the first limiting surface when the roller brush mounting side plate rotates from the unlocking working position to the locking working position;
[0027] Specifically, along the direction from the first limiting block to the second limiting block, the limiting guiding surface gradually inclines towards the first limiting end side.
[0028] Along the direction in which the roller brush mounting side plate rotates from the unlocking working position to the locking working position, the two ends of the first limiting block are respectively formed as a first limiting end and a second limiting end. It can be understood that when the roller brush mounting side plate rotates from the unlocking working position to the locking working position, the first limiting end will be opposite to the third limiting block prior to the second limiting end.
[0029] With the above structure, the setting of the limiting guiding surface enables the first limiting block to move more reliably from being opposite to the limiting inlet and outlet to being opposite to the third limiting block, and the structural design is reasonable.
[0030] Further, the locking mating inner wall is provided with a first rotation limiting block and a second rotation limiting block on the side of the second limiting surface away from the first limiting surface, and the first rotation limiting block and the second rotation limiting block are respectively located on both sides of the movement track of the first limiting block. When the roller brush mounting side plate rotates to the locking position, the first limiting block abuts against the first rotation limiting block, and when the roller brush mounting side plate rotates to the unlocking position, the first limiting block abuts against the second rotation limiting block.
[0031] With the above structure, the setting of the first rotation limiting block and the second rotation limiting block can limit the movement range of the first limiting block to prevent it from over-moving; that is, it limits the movement range of the roller brush mounting side plate and improves the user experience.
[0032] Further, a plurality of the first limiting blocks are provided, and the plurality of the first limiting blocks are arranged at intervals along the rotation direction of the roller brush mounting side plate; correspondingly, the number of the second limiting blocks provided is matched with the number of the first limiting blocks and is arranged in a one-to-one correspondence, and the number of the limiting inlets and outlets is matched with the number of the first limiting blocks. Moreover, in the rotation direction of the roller brush mounting side plate, the interval between the limiting inlets and outlets is matched with the interval between the first limiting blocks.
[0033] With the above structure, the locking cooperation between the first mounting locking structure and the second mounting locking structure can be made more stable and reliable.
[0034] Further, the plurality of the second limiting blocks are connected end to end in sequence to form a whole.
[0035] With the above structure, the structure of the second limiting block is more reasonable, which is convenient for actual production.
[0036] Further, the outer periphery of the plurality of the second limiting blocks formed into a whole is matched with the inner diameter of the roller brush disassembly and assembly opening.
[0037] With the above structure, the plurality of the second limiting blocks formed into a whole can shield the internal structure, which not only increases the aesthetic degree of the appearance of the roller brush mechanism, but also can prevent foreign objects from entering the roller brush accommodation cavity through the roller brush disassembly and assembly opening, and can also increase the service life of the roller brush mechanism.
[0038] Further, the roller brush mounting side plate is provided with a first rotation locking structure. Correspondingly, the roller brush disassembly and assembly opening is provided with a second rotation locking structure that is matched with the first rotation locking structure; the first rotation locking structure and the second rotation locking structure are configured to cooperate with each other when the roller brush mounting side plate is in the locking working position so that a certain operating force is required for the rotation of the roller brush mounting side plate.
[0039] With the above structure, the setting of the first rotation locking structure and the second rotation locking structure makes it necessary to apply a certain operating force to rotate the roller brush mounting side plate when it is in the locking working position, which can prevent accidental rotation of the roller brush mounting side plate when it is in the locking working position and ensure the reliability and stability of the mechanism.
[0040] Further, when the roller brush mounting side plate moves to the position of the roller brush disassembly and assembly opening, the locking cooperation side wall of the roller brush mounting side plate is arranged opposite to the locking cooperation inner wall of the roller brush disassembly and assembly opening.
[0041] The first rotational locking structure includes a rotational locking protrusion protruding from the locking mating side wall; the second rotational locking structure includes a rotational locking mating protrusion protruding from the inner wall of the locking mating, and a locking gear groove matching the rotational locking protrusion is recessed on one side of the rotational locking mating protrusion facing the locking mating side wall. When the roller brush mounting side plate rotates to the locking position, the rotational locking protrusion is located in the locking gear groove.
[0042] With the above structure, when the roller brush mounting side plate rotates to the locking position, the rotational locking protrusion is located in the locking gear groove. At this time, when the roller brush mounting side plate rotates from the locking position to the unlocking position, the rotational locking protrusion needs to disengage from the locking gear groove, so a certain operating force is required to realize the functions of the first rotational locking structure and the second rotational locking structure; specifically, the locking gear groove is an arc-shaped groove.
[0043] Further, the rotational locking mating protrusion extends along the rotational direction of the roller brush mounting side plate from the locking working position to the unlocking working position, and along the rotational direction of the roller brush mounting side plate from the locking working position to the unlocking working position, the side of the rotational locking mating protrusion facing the locking mating side wall gradually approaches the locking mating side wall.
[0044] The rotational locking protrusion has an interference design with at least one end of the side of the rotational locking mating protrusion facing the locking mating side wall where the locking gear groove is provided to provide an operating force. With the above structure, the special design of the side of the rotational locking mating protrusion facing the locking mating side wall can play a guiding role when the rotational locking protrusion moves towards the locking gear groove side, facilitating its movement to this side, and the above structural design is reasonable.
[0045] Further, an unlocking gear groove matching the rotational locking protrusion is recessed on one side of the rotational locking mating protrusion facing the locking mating side wall. When the roller brush mounting side plate rotates to the unlocking position, the rotational locking protrusion is located in the unlocking gear groove.
[0046] With the above structure, the setting of the unlocking gear groove can prevent the rotational locking protrusion from affecting the movement of the roller brush mounting side plate to the roller brush disassembly and assembly opening when pulling and disassembling the roller brush assembly or inserting and installing the roller brush assembly; specifically, the unlocking gear groove is an arc-shaped groove.
[0047] Further, an operating member for facilitating the user to rotate the roller brush mounting side plate is provided on the side of the roller brush mounting side plate opposite to the side where the roller brush is installed.
[0048] With the above structure, the setting of the operating member facilitates the user to operate the roller brush mounting side plate, such as pushing, pulling, rotating the roller brush mounting side plate, etc.
[0049] Furthermore, on the side of the roller brush mounting side plate opposite to the side where the roller brush is mounted, there is an operating member receiving groove for receiving the operating member, and the operating member is rotatably arranged in the operating member receiving groove.
[0050] With the above structure, when the operating member is not in use, it can be received in the operating member receiving groove, which is not only more aesthetically pleasing but also avoids having an adverse impact during the operation of the roller brush mechanism.
[0051] Furthermore, the operating member receiving groove includes a receiving groove bottom surface and a receiving groove side surface perpendicular to the receiving groove bottom surface. The operating member is rotatably connected to the receiving groove side surface, and when the operating member is received in the operating member receiving groove, the operating member is in contact with the receiving groove bottom surface.
[0052] With the above structure, the installation setting of the operating member and the structure of the operating member receiving groove are more reasonable.
[0053] Furthermore, an operating locking protrusion is convexly provided on the receiving groove side surface of the operating member receiving groove.
[0054] With the above structure, when the operating member is received in the operating member receiving groove, the operating locking protrusion will interfere with the operating member to a certain extent, so that a certain operating force is required to rotate the operating member to a non-receiving state, effectively avoiding accidental rotation of the operating member when it is received in the operating member receiving groove.
[0055] Furthermore, the operating member has a semi-circular ring structure, and both ends of the operating member are rotatably connected to the receiving groove side surface of the operating member receiving groove.
[0056] With the above structure, the structural design of the operating member is more reasonable and convenient for actual use.
[0057] Furthermore, at the rotation connection end of the roller brush, a roller brush connection groove is formed by inward depression at the rotation axis of the roller brush, and a first roller brush rotation shaft is convexly provided on the bottom surface of the roller brush connection groove at the rotation axis of the roller brush;
[0058] Correspondingly, on the roller brush mounting side plate, a roller brush connection protrusion is convexly formed at the rotation axis of the roller brush, which is matched with the roller brush connection groove and can extend into the roller brush connection groove. A first roller brush rotation groove is formed by depression at the rotation axis of the roller brush connection protrusion, which is matched with the first roller brush rotation shaft for the first roller brush rotation shaft to extend into.
[0059] With the above structure, the rotational connection between the rotary brush and the mounting side plate of the rotary comb is realized, and the structural design is reasonable and reliable.
[0060] Furthermore, a bearing is provided between the first rotary brush shaft and the rotary brush rotating groove.
[0061] With the above structure, the provision of the bearing enables the rotation between the first rotary brush shaft and the rotary brush rotating groove to be smoother and more reliable.
[0062] Furthermore, the rotary brush mechanism includes a second rotary brush shaft rotatably provided at the end of the second rotary brush receiving cavity. The second rotary brush shaft extends along the rotation axis of the rotary brush, and the rotation axis of the second rotary brush shaft is collinear with the rotation axis of the rotary brush. When the rotary brush extends into the rotary brush receiving cavity, the free end of the rotary brush is connected to the second rotary brush shaft.
[0063] With the above structure, when the user extends the rotary brush into the rotary brush receiving cavity, the free end of the rotary brush of the rotary comb will be connected to the second rotary brush shaft provided at the end of the second rotary brush receiving cavity, making the rotation of the rotary brush more stable and reliable.
[0064] Furthermore, a second rotary brush rotating groove that matches the second rotary brush shaft for the second rotary brush shaft to extend into is provided at the rotation axis of the free end of the rotary brush.
[0065] A rotation limiting card slot is provided on the second rotary brush shaft, and a rotation limiting protrusion is provided on the second rotary brush rotating groove. In the state where the second rotary brush shaft extends into the second rotary brush rotating groove, the rotation limiting protrusion is snapped into the rotation limiting card slot to limit the relative rotational movement between the rotary brush and the second rotary brush shaft.
[0066] With the above structure, the connection between the free end of the rotary brush and the second rotary brush shaft is realized.
[0067] Furthermore, the rotary brush mechanism includes a drive assembly for driving the rotation of the second rotary brush shaft.
[0068] Specifically, the drive assembly includes a drive motor, a first pulley, a second pulley, and a drive belt. The first pulley is provided on the output shaft of the drive motor, the second pulley is provided on the second rotary brush shaft, and the drive belt is wound around the outer circumferences of the first pulley and the second pulley.
[0069] With the above structure, the driving assembly drives the rotation of the second brush rotating shaft, thereby driving the rotation of the brush, enabling the brush to clean the operation surface more efficiently; the driving assembly uses the driving motor, the first pulley, the second pulley and the driving belt, which is convenient for spatial layout and enables the driving assembly to better drive the rotation of the second brush rotating shaft.
[0070] Further, the brush mechanism includes a seal for sealing between the brush mounting side plate and the brush disassembly and assembly opening.
[0071] Specifically, the seal is sleeved on the brush mounting side plate and is located on the side of the second limiting block facing the first limiting block.
[0072] With the above structure, the setting of the seal can seal between the brush mounting side plate and the brush disassembly and assembly opening, preventing debris from being ejected between the brush mounting side plate and the brush disassembly and assembly opening when the brush rotates at high speed, causing unnecessary danger.
[0073] A cleaning device includes the above brush mechanism.
[0074] With the above structure, the user can disassemble and assemble the brush assembly very conveniently, greatly enhancing the user experience; specifically, the cleaning device is a vacuum cleaner.
[0075] Compared with the prior art, the present utility model has the following beneficial effects:

[0093] The following will describe the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.
[0094] Refer to Figures 1 to 7 , the present utility model provides a roller brush mechanism, which is arranged on a cleaning device capable of traveling on an operation surface, and includes:
[0095] A base member 1, the base member 1 is provided with a roller brush receiving cavity 101, the roller brush receiving cavity 101 is configured to extend along a direction perpendicular to the traveling direction of the cleaning device, and the extending direction of the roller brush 201 is parallel to the operation surface. The two ends of the roller brush receiving cavity 101 in its extending direction are respectively formed as a first roller brush receiving cavity end 1011 and a second roller brush receiving cavity end 1012, and the first roller brush receiving cavity end 1011 extends away from the second roller brush receiving cavity end 1012 side and penetrates through the base member 1 to form a roller brush disassembly and assembly opening 102;
[0096] A roller brush assembly 2, the roller brush assembly 2 includes a roller brush 201 and a roller brush mounting side plate 202. The roller brush rotation connection end 2011 of the roller brush 201 is rotationally connected to the roller brush mounting side plate 202, and the other end is formed as a roller brush free end 2012;
[0097] The roller brush mounting side plate 202 is configured to be able to drive the roller brush 201 to extend into the roller brush receiving cavity 101 until the roller brush mounting side plate 202 moves to the roller brush disassembly and assembly opening 102; and the roller brush mounting side plate 202 can rotate relative to the roller brush disassembly and assembly opening 102 to achieve locking and unlocking of the two.
[0098] It should be noted that when the roller brush mounting side plate 202 and the roller brush disassembly and assembly opening 102 are locked, the roller brush mounting side plate 202 is restricted from moving relative to the roller brush disassembly and assembly opening 102 in the disassembly and assembly direction of the roller brush 201.
[0099] During use, the roller brush mechanism is arranged on the cleaning device. When the cleaning device travels, the rotating roller brush 201 can clean the operation surface. Specifically, the roller brush receiving cavity 101 is a lower-opening cavity; the operation surface is usually the ground.
[0100] With the above structure, the user can conveniently disassemble the roller brush assembly 2 from the base member 1 or install the roller brush assembly 2 onto the base member 1, facilitating the user's daily cleaning and maintenance of the roller brush 201. For example, when a large amount of hair is wound around the roller brush 201 and needs to be cleaned;
[0101] Specifically, when disassembly is required, the user only needs to operate the roller brush mounting side plate 202 to rotate it relative to the roller brush disassembly and assembly opening 102 to unlock it from the roller brush disassembly and assembly opening 102. At this time, the user can pull out the roller brush assembly 2 from the roller brush disassembly and assembly opening 102, and the user can clean the roller brush 201;
[0102] When installation is required, the user only needs to align the free end 2012 of the roller brush 201 with the roller brush disassembly and assembly opening 102, and then insert the roller brush 201 into the roller brush receiving cavity 101 through the roller brush disassembly and assembly opening 102 until the roller brush mounting side plate 202 moves to the roller brush disassembly and assembly opening 102; the user only needs to rotate the roller brush mounting side plate 202 to lock it with the roller brush disassembly and assembly opening 102. At this time, the roller brush assembly 2 is installed onto the base member 1;
[0103] The above structure is convenient to operate, greatly enhancing the user experience.
[0104] Refer to Figures 1 to 5 Furthermore, the roller brush mounting side plate 202 is provided with a first installation locking structure 3. Correspondingly, the roller brush disassembly and assembly opening 102 is provided with a second installation locking structure 4 that matches the first installation locking structure 3;
[0105] During the rotation of the roller brush mounting side plate 202 relative to the roller brush disassembly and assembly opening 102, there are a locking working position and an unlocking working position, and the first installation locking structure 3 and the second installation locking structure 4 are configured to lock when the roller brush mounting side plate 202 rotates to the locking position and unlock when the roller brush mounting side plate 202 rotates to the unlocking position.
[0106] With the above structure, the setting of the first installation locking structure 3 and the second installation locking structure 4 enables the roller brush mounting side plate 202 to be unlocked and locked with the roller brush disassembly and assembly opening 102 when it rotates relative to the roller brush disassembly and assembly opening 102; the structural design is reasonable.
[0107] Refer to Figures 1 to 5 Furthermore, when the roller brush mounting side plate 202 moves to the roller brush disassembly and assembly opening 102, the locking cooperation side wall 2021 of the roller brush mounting side plate 202 is disposed opposite to the locking cooperation inner wall 1021 of the roller brush disassembly and assembly opening 102;
[0108] The first installation locking structure 3 includes a first limiting block 301 and a second limiting block 302 provided on the locking and mating side wall 2021. The first limiting block 301 and the second limiting block 302 are spaced apart in the disassembly and assembly direction of the roller brush 201. When the roller brush installation side plate 202 enters the roller brush disassembly and assembly port 102, the first limiting block 301 enters the roller brush disassembly and assembly port 102 prior to the second limiting block 302;
[0109] The second installation locking structure 4 includes a third limiting block 401 and a limiting inlet and outlet 402 provided on the locking and mating inner wall 1021. The third limiting block 401 and the limiting inlet and outlet 402 are distributed along the rotation direction of the roller brush installation side plate 202;
[0110] In the installation direction of the roller brush 201, both end faces of the third limiting block 401 are respectively formed as a first limiting surface 4011 and a second limiting surface 4012, and the distance between the first limiting surface 4011 and the second limiting surface 4012 is not greater than the interval distance between the first limiting block 301 and the second limiting block 302; in the rotation direction of the roller brush installation side plate 202, the width of the limiting inlet and outlet 402 matches the width of the first limiting block 301 so that the first limiting block 301 can move through and move to the side of the second limiting surface 4012 away from the first limiting surface 4011.
[0111] In the installation direction of the roller brush 201, both end faces of the third limiting block 401 are respectively formed as a first limiting surface 4011 and a second limiting surface 4012, which can be understood as: when the roller brush 201 is installed and extends into the roller brush receiving cavity 101, the first limiting block 301 will first pass through the first limiting surface 4011 and then pass through the second limiting surface 4012.
[0112] With the above structure, during installation, the user needs to align the first limiting block 301 with the selected limiting inlet and outlet 402. When the roller brush installation side plate 202 moves to the roller brush disassembly and assembly port 102, the first limiting block 301 will pass through the limiting inlet and outlet 402 and move to the side of the second limiting surface 4012 of the third limiting block 401. Then the user needs to rotate the roller brush installation side plate 202 so that the first limiting block 301 is opposite to the second limiting surface 4012 of the third limiting block 401. At this time, the third limiting block 401 is located between the first limiting block 301 and the second limiting block 302, thereby restricting the movement of the roller brush installation side plate 202 relative to the roller brush disassembly and assembly port 102 in the disassembly and assembly direction of the roller brush 201. The locking between the roller brush installation side plate 202 and the roller brush disassembly and assembly port 102 is achieved;
[0113] When disassembling, the user needs to rotate the roller brush mounting side plate 202 so that the first limiting block 301 moves from being opposite to the third limiting block 401 to being opposite to the limiting inlet / outlet 402. At this time, the restriction of the first limiting block 301 and the second limiting block 302 on the third limiting block 401 is released, and the user can then pull out the roller brush 201 assembly from the base member 1; the above structure is reasonably designed.
[0114] Refer to Figure 4 , further, along the direction of the roller brush mounting side plate 202 rotating from the unlocking working position to the locking working position, the two ends of the first limiting block 301 are respectively formed as a first limiting end 3011 and a second limiting end 3012. At least one side of the side wall of the second limiting end 3012 facing the second limiting block 302 is configured as a limiting guiding surface 3013, and the limiting guiding surface 3013 is used to guide the first limiting block 301 to move to be opposite to the side of the second limiting surface 4012 away from the first limiting surface 4011 when the roller brush mounting side plate 202 rotates from the unlocking working position to the locking working position;
[0115] Specifically, along the direction from the first limiting block 301 to the second limiting block 302, the limiting guiding surface 3013 gradually inclines towards the first limiting end 3011 side.
[0116] Along the direction of the roller brush mounting side plate 202 rotating from the unlocking working position to the locking working position, the two ends of the first limiting block 301 are respectively formed as a first limiting end 3011 and a second limiting end 3012. It can be understood that when the roller brush mounting side plate 202 rotates from the unlocking working position to the locking working position, the first limiting end 3011 will be opposite to the third limiting block 401 prior to the second limiting end 3012.
[0117] With the above structure, the setting of the limiting guiding surface 3013 can enable the first limiting block 301 to move more reliably from being opposite to the limiting inlet / outlet 402 to being opposite to the third limiting block 401, and the structural design is reasonable.
[0118] Refer to Figure 3, Further, a first rotation limiting block 5 and a second rotation limiting block 6 are provided on the inner wall 1021 of the locking fit on the side of the second limiting surface 4012 away from the first limiting surface 4011. The first rotation limiting block 5 and the second rotation limiting block 6 are respectively located on both sides of the movement track of the first limiting block 301. When the roller brush mounting side plate 202 rotates to the locking position, the first limiting block 301 abuts against the first rotation limiting block 5. When the roller brush mounting side plate 202 rotates to the unlocking position, the first limiting block 301 abuts against the second rotation limiting block 6.
[0119] With the above structure, the first rotation limiting block 5 and the second rotation limiting block 6 can limit the movement range of the first limiting block 301 to prevent it from over-moving; that is, limit the movement range of the roller brush mounting side plate 202, improving the user experience.
[0120] Refer to Figures 3 to 5 , Further, a plurality of the first limiting blocks 301 are provided, and the plurality of first limiting blocks 301 are arranged at intervals along the rotation direction of the roller brush mounting side plate 202; correspondingly, the number of the second limiting blocks 302 is matched with the number of the first limiting blocks 301 and is arranged in a one-to-one correspondence. The number of the limiting inlets and outlets 402 is matched with the number of the first limiting blocks 301, and the intervals between the limiting inlets and outlets 402 are matched with the intervals between the first limiting blocks 301 in the rotation direction of the roller brush mounting side plate 202.
[0121] With the above structure, the locking fit between the first installation locking structure 3 and the second installation locking structure 4 can be made more stable and reliable.
[0122] Refer to Figure 4 , Further, a plurality of the second limiting blocks 302 are connected end to end in sequence to form an integral body.
[0123] With the above structure, the structure of the second limiting block 302 is more reasonable, facilitating actual production.
[0124] Refer to Figure 1 , Further, the outer periphery of the plurality of second limiting blocks 302 formed into an integral body is matched with the inner diameter of the roller brush disassembly and assembly opening 102.
[0125] With the above structure, the plurality of second limiting blocks 302 formed into an integral body can shield the internal structure, not only increasing the aesthetic appearance of the roller brush mechanism, but also preventing foreign objects from entering the roller brush accommodation cavity 101 through the roller brush disassembly and assembly opening 102, and increasing the service life of the roller brush mechanism.
[0126] Refer to Figures 3 to 5 Further, a first rotation locking structure 7 is provided on the roller brush mounting side plate 202. Correspondingly, a second rotation locking structure 8 matching the first rotation locking structure 7 is provided at the roller brush disassembly and assembly opening 102. The first rotation locking structure 7 and the second rotation locking structure 8 are configured to cooperate with each other when the roller brush mounting side plate 202 is in the locking working position, so that a certain operating force is required for the rotation of the roller brush mounting side plate 202.
[0127] With the above structure, the first rotation locking structure 7 and the second rotation locking structure 8 are provided, so that a certain operating force is required for the rotation of the roller brush mounting side plate 202 when it is in the locking working position, which can avoid accidental rotation of the roller brush mounting side plate 202 when it is in the locking working position, and ensure the reliability and stability of the mechanism.
[0128] Further, when the roller brush mounting side plate 202 moves to the roller brush disassembly and assembly opening 102, the locking cooperation side wall 2021 of the roller brush mounting side plate 202 is disposed opposite to the locking cooperation inner wall 1021 of the roller brush disassembly and assembly opening 102.
[0129] The first rotation locking structure 7 includes a rotation locking protrusion 701 protruding from the locking cooperation side wall 2021. The second rotation locking structure 8 includes a rotation locking cooperation protrusion 801 protruding from the locking cooperation inner wall 1021. A locking gear groove 8011 matching the rotation locking protrusion 701 is recessed on the side of the rotation locking cooperation protrusion 801 facing the locking cooperation side wall 2021. When the roller brush mounting side plate 202 rotates to the locking position, the rotation locking protrusion 701 is located in the locking gear groove 8011.
[0130] With the above structure, when the roller brush mounting side plate 202 rotates to the locking position, the rotation locking protrusion 701 is located in the locking gear groove 8011. At this time, when the roller brush mounting side plate 202 rotates from the locking position to the unlocking position, the rotation locking protrusion 701 needs to disengage from the locking gear groove 8011, so a certain operating force is required, thereby realizing the functions of the first rotation locking structure 7 and the second rotation locking structure 8. Specifically, the locking gear groove 8011 is an arc-shaped groove.
[0131] Further, the rotation locking engagement projection 801 extends along the rotation direction from the locking working position to the unlocking working position of the roller brush mounting side plate 202, and along the rotation direction of the roller brush mounting side plate 202 from the locking working position to the unlocking working position, the side of the rotation locking engagement projection 801 facing the locking engagement side wall 2021 is gradually arranged closer to the locking engagement side wall 2021.
[0132] The rotation locking projection 701 has at least a certain interference design with at least one end of the rotation locking engagement projection 801 facing the locking engagement side wall 2021 where the locking gear groove 8011 is provided, so as to provide an operating force. With the above structure, the special design of the side of the rotation locking engagement projection 801 facing the locking engagement side wall 2021 can play a certain guiding role when the rotation locking projection 701 moves towards the locking gear groove 8011 side, facilitating its movement towards this side, and the above structural design is reasonable.
[0133] Further, a unlocking gear groove 8012 matching the rotation locking projection 701 is recessed on the side of the rotation locking engagement projection 801 facing the locking engagement side wall 2021, and when the roller brush mounting side plate 202 rotates to the unlocking position, the rotation locking projection 701 is located in the unlocking gear groove 8012.
[0134] With the above structure, the setting of the unlocking gear groove 8012 can avoid the rotation locking projection 701 affecting the movement of the roller brush mounting side plate 202 to the roller brush disassembly and assembly opening 102 when pulling and disassembling the roller brush assembly 2 or inserting and installing the roller brush assembly 2; specifically, the unlocking gear groove 8012 is an arc-shaped groove.
[0135] Refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 6 Further, an operating member 9 for facilitating the user to rotate the roller brush mounting side plate 202 is provided on the side of the roller brush mounting side plate 202 opposite to the side where the roller brush 201 is installed.
[0136] With the above structure, the setting of the operating member 9 facilitates the user to operate the roller brush mounting side plate 202, such as pushing, pulling, rotating and other operations on the roller brush mounting side plate 202.
[0137] Refer to Figure 6 Further, an operating member receiving groove 2022 for receiving the operating member 9 is provided on the side of the roller brush mounting side plate 202 opposite to the side where the roller brush 201 is installed, and the operating member 9 is rotatably arranged in the operating member receiving groove 2022.
[0138] With the above structure, when the operating member 9 is not in use, it can be stored in the operating member storage groove 2022, which is not only more beautiful but also avoids having an adverse effect during the operation of the roller brush mechanism.
[0139] Furthermore, the operating member storage groove 2022 includes a storage groove bottom surface 2021a and a storage groove side surface 2021b perpendicular to the storage groove bottom surface 2021a. The operating member 9 is rotatably connected to the storage groove side surface 2021b, and when the operating member 9 is stored in the operating member storage groove 2022, the operating member 9 is in contact with the storage groove bottom surface 2021a.
[0140] With the above structure, the installation of the operating member 9 and the structure of the operating member storage groove 2022 are more reasonable.
[0141] Furthermore, an operating locking protrusion 2021c is protrudingly provided on the side surface 2021b of the operating member storage groove 2022.
[0142] With the above structure, when the operating member 9 is stored in the operating member storage groove 2022, the operating locking protrusion 2021c will interfere with the operating member 9 to a certain extent, so that a certain operating force is required to rotate the operating member 9 to a non-stored state, effectively avoiding accidental rotation of the operating member 9 when it is stored in the operating member storage groove 2022.
[0143] Furthermore, the operating member 9 has a semi-circular ring structure, and both ends of the operating member 9 are rotatably connected to the side surface 2021b of the operating member storage groove 2022.
[0144] With the above structure, the structural design of the operating member 9 is more reasonable and convenient for actual use.
[0145] Refer to Figure 6 , furthermore, the roller brush rotation connection end 2011 of the roller brush 201 is recessed inward at the rotation axis of the roller brush 201 to form a roller brush connection groove 2013, and a first roller brush rotation shaft 2014 is protrudingly provided on the bottom surface of the roller brush connection groove 2013 at the rotation axis of the roller brush 201;
[0146] Correspondingly, the roller brush mounting side plate 202 protrudes at the rotation axis of the roller brush 201 to form a roller brush connection protrusion 2023 that matches the roller brush connection groove 2013 and can extend into the roller brush connection groove 2013. The roller brush connection protrusion 2023 is recessed at the rotation axis of the roller brush 201 to form a first roller brush rotation groove 2024 that matches the first roller brush rotation shaft 2014 for the first roller brush rotation shaft 2014 to extend into.
[0147] With the above structure, the rotational connection between the rotary brush 201 and the mounting side plate of the rotary comb is realized, and the structural design is reasonable and reliable.
[0148] Further, a bearing 10 is provided between the first rotary brush rotating shaft 2014 and the rotary brush 201 rotating groove.
[0149] With the above structure, the setting of the bearing 10 can make the rotation between the first rotary brush rotating shaft 2014 and the rotary brush 201 rotating groove smoother and more reliable.
[0150] Refer to Figure 2 and Figure 7 , further, the rotary brush mechanism includes a second rotary brush rotating shaft 11 rotatably provided at the end 1012 of the second rotary brush receiving cavity. The second rotary brush rotating shaft 11 extends along the rotation axis of the rotary brush 201, and the rotation axis of the second rotary brush rotating shaft 11 is collinear with the rotation axis of the rotary brush 201. When the rotary brush 201 extends into the rotary brush receiving cavity 101, the free end 2012 of the rotary brush is connected to the second rotary brush rotating shaft 11.
[0151] With the above structure, when the user extends the rotary brush 201 into the rotary brush receiving cavity 101, the free end 2012 of the rotary brush of the rotary comb will be connected to the second rotary brush rotating shaft 11 provided at the end 1012 of the second rotary brush receiving cavity, making the rotation of the rotary brush 201 more stable and reliable.
[0152] Further, the free end 2012 of the rotary brush is provided with a second rotary brush rotating groove 2015 matching the second rotary brush rotating shaft 11 for the second rotary brush rotating shaft 11 to extend into at the rotation axis of the rotary brush 201;
[0153] A rotation limiting card slot 1101 is provided on the second rotary brush rotating shaft 11, and a rotation limiting protrusion 2015a is provided on the second rotary brush rotating groove 2015. In the state where the second rotary brush rotating shaft 11 extends into the second rotary brush rotating groove 2015, the rotation limiting protrusion 2015a is snapped into the rotation limiting card slot 1101 to limit the relative rotational movement between the rotary brush 201 and the second rotary brush rotating shaft 11.
[0154] With the above structure, the connection between the free end 2012 of the rotary brush and the second rotary brush rotating shaft 11 is realized.
[0155] Refer to Figure 7 , further, the rotary brush mechanism includes a driving component 12 for driving the second rotary brush rotating shaft 11 to rotate.
[0156] Specifically, the driving assembly 12 includes a driving motor 1201, a first pulley 1202, a second pulley 1203, and a driving belt 1204. The first pulley 1202 is disposed on the output shaft of the driving motor 1201, the second pulley 1203 is disposed on the second brush rotating shaft 11, and the driving belt 1204 is wound around the outer circumferences of the first pulley 1202 and the second pulley 1203.
[0157] With the above structure, the driving assembly 12 drives the second brush rotating shaft 11 to rotate, thereby driving the rotation of the brush 201, enabling the brush 201 to clean the operation surface more efficiently; the driving assembly 12 adopts the driving motor 1201, the first pulley 1202, the second pulley 1203, and the driving belt 1204, which is convenient for spatial layout and enables the driving assembly 12 to better drive the rotation of the second brush rotating shaft 11.
[0158] Refer to Figure 4 , further, the brush mechanism includes a seal 13 for sealing between the brush mounting side plate 202 and the brush disassembly and assembly opening 102.
[0159] Specifically, the seal 13 is sleeved on the brush mounting side plate 202 and is located on the side of the second limit block 302 facing the first limit block 301.
[0160] With the above structure, the setting of the seal 13 can seal between the brush mounting side plate 202 and the brush disassembly and assembly opening 102, preventing debris from being ejected between the brush mounting side plate 202 and the brush disassembly and assembly opening 102 when the brush 201 rotates at a high speed, causing unnecessary danger.
[0161] Refer to Figures 1 to 7 , a cleaning device includes the above brush mechanism.
