Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning machinery, and in particular to a detachable brush roller assembly. BACKGROUND

[0002] The scrubber with water dust circulation technology drives the cleaning cylinder to wipe the ground through the operation of the motor. The cleaning cylinder usually adopts a sponge cylinder structure. Meanwhile, the ground cleaner is also equipped with a water supply system to clean the cleaning cylinder, thereby achieving the cleaning of the ground.

[0003] In order to clean the cleaning cylinder, a closed cleaning space in communication with the water supply system is usually provided to clean the local roller. Clean water is provided to clean the cleaning cylinder, and then the sewage after cleaning the cleaning cylinder is pumped away. In the rear part of the closed cleaning space, a brush roller is arranged in the cleaning head housing. The brush roller is used to wind up the solid waste and hair on the surface of the sponge roller after cleaning in the sealed cleaning space, and directly sweeps into the garbage box.

[0004] Chinese patent document CN113303736A discloses a cleaning head and a cleaning tool for cleaning tools, comprising: a first roller; a sink assembly with a flip cover arranged above the first roller; an integrally detachable second roller assembly comprising a second roller arranged behind the first roller in the rotation direction; and an integrally detachable garbage box assembly arranged behind the second roller. By arranging the sink assembly with a flip cover, when larger garbage enters the sink, the flip cover can be opened to remove the garbage, and the sink can be cleaned or washed in the water flow without the need to disassemble the sponge roller to remove the garbage, which is convenient and fast. The integrally detachable second roller assembly and garbage box assembly make it more convenient and fast to clean the brush and garbage box. In addition, the garbage box can be automatically opened by a button, reducing the contact between people and garbage, and being more sanitary. However, in the water dust circulation ground cleaner configuration without a brush roller, a garbage box upper cover is usually arranged above the garbage box to block the view and beautify the visual effect on the upper surface of the cleaning head housing. In the ground cleaner configuration with a brush roller, the brush roller assembly is usually arranged directly above the garbage box, so that the garbage swept by the brush can directly fall into the garbage box. However, the upper cover of the brush roller assembly also serves as the upper cover plate of the garbage box. When it is necessary to dump the garbage accumulated in the garbage box, the brush roller assembly needs to be removed first, and then the garbage box can be removed from top to bottom. Since the frequency of dumping the garbage box is obviously more than the frequency of cleaning the brush roller, the user will be annoyed by the additional action of removing the brush assembly for dumping the garbage, and the user experience is poor. SUMMARY

[0005] The technical problem solved by the present application is to provide a detachable side-extractable brush roller assembly, which provides a structure for extracting the brush roller from the side, and can be operated conveniently without separating the entire brush roller assembly from the cleaning appliance, thereby improving the user experience.

[0006] To solve the above problems, the present application provides a detachable brush roller assembly, which comprises a brush roller, a brush roller support and a coupling structure. The brush roller comprises a brush roller body, a driving end and a detachable end. The driving end drives the rotation of the brush roller, and the detachable end is provided with a detachable member connected with the brush roller. The brush roller support is provided with a motor and a transmission assembly at one end of the support and in transmission connection with the motor, so as to drive the driving end. The coupling structure is arranged between the brush roller and the brush roller support, so as to facilitate the separation of the two.

[0007] On the basis of the above technical solution, the present application can also be improved as follows.

[0008] In one embodiment, the driving end extends outwardly from the brush roller body, and the two are an integral whole. The driving end can be axially separated from the transmission assembly.

[0009] On the basis of the above technical solution, the present application can also be improved as follows.

[0010] In one embodiment, the detachable member comprises a detachable member body, a connecting end provided at one end of the detachable member body and connected with the detachable brush roller body, and an operating end provided at the other end of the detachable member body. The transverse width of the detachable member body is greater than that of the connecting end.

[0011] In one embodiment, the transverse width of the operating end is greater than that of the detachable member body.

[0012] On the basis of the above technical solution, the present application can also be improved as follows.

[0013] In one embodiment, the coupling structure is a buckle structure, which comprises a buckle or a slot provided on the detachable member and a slot or a buckle provided on the brush roller support, and the two can be buckled together.

[0014] In one embodiment, the buckle structure comprises a slot provided on the detachable member and a clamping protrusion provided on the brush roller support and matched with the slot. At least one side of the clamping protrusion is a slope.

[0015] In one embodiment, the slot is a circular arc.

[0016] On the basis of the above technical solution, the present application can also be improved as follows.

[0017] In one of the embodiments, the transmission assembly comprises a rotating gear set.

[0018] Based on the above technical solution, the application can be further improved as follows.

[0019] In one of the embodiments, the brush roller support is provided with an empty space for accommodating the detachable component.

[0020] Based on the above technical solution, the application can be further improved as follows.

[0021] In one of the embodiments, the coupling structure is a magnetic attraction structure, which comprises a magnetic body provided on the detachable component and a magnetic body provided on the brush roller support, and the two magnetic bodies are magnetically attracted to each other.

[0022] In one of the embodiments, the magnetic body provided on the brush roller support is enclosed in the inner wall of the brush roller support.

[0023] In one of the embodiments, the magnetic body provided on the detachable component can be directly taken out or placed on one side of the detachable component, and the one side of the detachable component is provided with an open magnetic body mounting groove.

[0024] The application provides a detachable brush roller assembly, which comprises a brush roller, a brush roller support and a coupling structure. The brush roller comprises a brush roller main body, a driving end and a detachable end, the driving end drives the brush roller to rotate, and the detachable end is provided with a detachable component which is rotationally connected to the brush roller. The brush roller support is provided with a motor and a transmission assembly which is transmissionally connected to the motor at one end of the brush roller support, and the transmission assembly drives the driving end. The coupling structure is arranged between the detachable brush roller and the brush roller support, so as to facilitate the separation of the two. In use, one end of the brush roller is connected to the transmission mechanism, and the other end of the brush roller is fixed to the brush roller support through the detachable component, so as to realize the working of the brush roller. When it is necessary to disassemble, the brush roller is unlocked from the one end of the brush roller support through the detachable component, and then the brush roller is pulled out along the length direction of the brush roller support. In this way, the brush roller can be taken out without separating the entire brush roller assembly from the cleaning appliance, which is convenient to operate. Meanwhile, since the transverse width of the detachable component is greater than the connecting end, the detachable component can provide greater strength, avoid irreversible deformation caused by stress during locking or disassembling, and avoid increasing the space in the structure, so that more effective space is left for the brush roller.

[0025] The beneficial effects of the present application: on the one hand, since the coupling structure is arranged between the brush roller and the brush roller support, it is convenient to separate the two, so that the user can not touch the brush roller with his hand when he needs to remove the brush roller, but only needs to directly grab the detachable end of the detachable brush roller and pull it out to the outside, then continue to hold the detachable end with his hand, and put the entire brush roller under the faucet for flushing, so that the brush roller can be flushed clean without directly touching it with his hand, which is convenient and not easy to dirty his hands. On the other hand, the side-extractable detachable brush roller assembly can be extracted along the length direction of the brush roller support after the brush roller and the brush roller support are unlocked by the detachable member. Since the upper cover of the brush roller assembly in the prior art also serves as the upper cover plate of the garbage box, when it is necessary to dump the garbage accumulated in the garbage box, the brush roller assembly needs to be removed first, and then the garbage box can be taken out from bottom to top. The advantage of this application is that the entire brush roller does not need to be separated from the cleaning appliance, but only needs to be extracted sideways. Since the frequency of dumping the garbage box is obviously more than the frequency of cleaning the brush roller, the negative emotions of the user caused by frequently opening the upper cover of the brush roller assembly can be overcome.

[0052] The scheme of the present application will be described in detail below with reference to the accompanying drawings.

[0053] As shown in Figures 1-9 The present application provides a detachable brush roller assembly, which comprises a brush roller 5, a brush roller support 1 and a coupling structure (not shown in the drawings). The detachable brush roller 5 comprises a brush roller body 51, a driving end (not shown in the drawings) and a detachable end (not shown in the drawings). The driving end drives the brush roller 5 to rotate. The detachable end is provided with a detachable member 53 which is rotationally connected with the brush roller 5. The brush roller support 1 is provided with a motor 2 and a transmission assembly 4 which is drivingly connected with the motor 2 at one end of the brush roller support 1. The transmission assembly 4 drives the driving end. The coupling structure is arranged between the detachable brush roller 5 and the brush roller support 1, so as to facilitate the separation of the two. In use, the brush roller 5 is connected with the transmission mechanism 4 at one end, and the other end of the brush roller 5 is fixed with the brush roller support 1 through the detachable member 53, so as to realize the working of the brush roller 5. When it is necessary to disassemble, the user removes the lock of the brush roller 5 with the brush roller support 1 at one end through the detachable member 53, and then pulls out the brush roller 5 along the length direction of the brush roller support 1. In this way, the brush roller can be taken out without separating the entire brush roller assembly from the cleaning appliance, which is convenient to operate. At the same time, since the transverse width of the detachable member main body 531 is greater than the transverse width of the connecting end 530, the detachable member can provide greater strength, avoid irreversible deformation caused by stress during locking or disassembling, and avoid increasing the space on the structure.

[0054] In this embodiment, when the user needs to remove the brush roller 5, he can not touch the brush roller 5 with his hands and only needs to directly grab the detachable end of the detachable brush roller 5 and pull it outward to extract the entire brush roller 5. Then, he continues to hold the detachable end and places the entire brush roller 5 under the faucet for flushing, which can realize flushing the brush roller without directly touching it with hands, is convenient and does not easily dirty the hands.

[0055] Specifically, in the embodiment shown in the drawings, as shown in the drawings, Figures 1 to 3 the detachable brush roller assembly includes a brush roller support 1 and a brush roller 5. The brush roller support 1 is provided with a motor 2 and a transmission assembly 4 connected to the motor 2 at one end of the brush roller support 1. As shown in the drawings, Figure 1 the brush roller 5 includes a brush roller body 51, a driving end (not marked in the drawings), and a detachable end (not marked in the drawings). The driving end is connected to the transmission assembly 4, and the driving end drives the brush roller body 51 to rotate.

[0056] As shown in the drawings, Figure 1 , Figure 3 In some embodiments, the driving end of the brush roller is a clamping joint 52 in the shape of a polygonal column extending outward from the brush roller body 51. Optionally, the regular polygonal column can be a column with a cross section in the shape of an equilateral triangle, a column with a cross section in the shape of a square, a column with a cross section in the shape of a regular hexagon, or a column with a cross section in the shape of a regular octagon. Of course, the driving end can also be a clamping joint 52 in the shape of a column with one or more edges extending outward from the brush roller body 51, as long as it can be driven by a corresponding column groove during rotation.

[0057] Referring to the drawings, Figure 5 , Figure 7 , Figure 9 In some embodiments, the detachable end of the brush roller is provided with a detachable member 53 connected to the brush roller 5 for rotation. The detachable member 53 and the brush roller support 1 are provided with a coupling structure.

[0058] Referring to the drawings, Figure 2 , Figure 5 , Figure 9 , Figure 10In some embodiments, the coupling mechanism is a snap structure, which includes a snap slot 534 provided on the detachable member 53 and a snap protrusion 13 provided on the brush roller support 1 and matched with the snap slot 534. At least one side of the snap protrusion 13 is a slope, and the snap slot 534 is a circular arc. When the detachable member 53 is rotated, the snap protrusion 13 rotates along the circular arc in the snap slot 534, and the two are pressed more and more tightly until the cooperation between them is the tightest when the detachable member 53 is rotated to the locking position. When it is needed to rotate to open the detachable member 53, the user needs to buckle the index finger into the empty position 11, and then use the thumb to hold the operating end 532 and turn the detachable member 53 outward. When the maximum elastic pressure between the snap protrusion 13 and the snap slot 534 is overcome, the user can easily rotate to open the locking position of the detachable member 53, and then pull it outward along the length direction of the brush roller support 1, so that the entire brush roller 5 can be pulled out.

[0059] Referring to Figure 5 , Figure 7 , Figure 9 , Figure 10 In some embodiments, the coupling mechanism is a magnetic structure, which includes a magnetic body 536 provided on the detachable member 53 and a magnetic body 12 provided on the brush roller support 1 and matched with the magnetic body 536. The magnetic body 536 of the detachable member 53 can be pressed into the magnetic body mounting port (not marked in the figure) of the detachable member 53 in a slightly interference fit manner. The four walls of the magnetic body mounting port are also provided with an elastic strip from the bottom to the top (not marked in the figure), which can increase the friction between the magnetic body and the magnetic body mounting port under the action of the four side wall elastic strips, so that the magnetic body will not fall out of the magnetic body mounting port during repeated opening and closing of the detachable member 53. The magnetic body 12 provided on the brush roller support 1 is provided on the inner wall of the brush roller support 1. Because the entire brush roller support 1 also serves as the upper cover of the cleaner garbage box, this design can prevent sewage from being further thrown into the inner wall 3 of the upper cover of the brush roller support 1. Of course, because there is a layer of thickness of the inner wall of the brush roller support 1, the magnetic body 12 will not fall out of the opening during repeated opening and closing of the detachable member 53. When the detachable member 53 is rotated, the suction force between the detachable member 53 and the brush roller support 1 changes with the distance between the magnetic body 12 and the magnetic body 536, and the suction force between them is the largest when the detachable member 53 is rotated to the locking position. When it is needed to rotate to open the detachable member 53, the user needs to buckle the index finger into the empty position 11, and then use the thumb to hold the operating end 532 and turn the detachable member 53 outward. When the maximum suction force between the magnetic body 12 and the magnetic body 536 is overcome, the user can easily rotate to open the locking position of the detachable member 53, and then pull it outward along the length direction of the brush roller support 1, so that the entire brush roller 5 can be pulled out.

[0060] Referring to Figure 1 , Figure 3 , Figure 4 In some embodiments, the transmission assembly 4 comprises a rotating gear set, a cover plate 3 is arranged on the brush cylinder support 1, a side plate 6 is arranged on the side of the brush cylinder support 1, the side plate 6 is used to protect the transmission assembly 4, and a cavity (not shown in the figure) for accommodating the transmission assembly 4 is arranged on one end surface of the brush cylinder support 1. The rotating gear set comprises a driving gear 41 mounted on the output shaft of the motor 2, a first driven gear 42 positioned in the cavity by a first pin (not shown in the figure), a second driven gear 43 positioned in the cavity by a second pin (not shown in the figure), and a driving gear 45 sleeved on the clamping joint 52. The motor 2 drives the driving gear 41 to rotate, further drives the first driven gear 42 to rotate, further drives the second driven gear 43 to rotate, further drives the driving gear 45 to rotate, and further drives the clamping joint 52 to rotate, thereby driving the entire brush cylinder 5 to rotate.

[0061] Referring to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figures 9 to 11 In some embodiments, the detachable component 53 comprises a detachable component body 531, a connecting end 530 arranged at one end of the detachable component body 531 and connected with the brush cylinder body 51, and an operating end 532 arranged at the other end of the detachable component body 531. The transverse width of the detachable component body 531 is greater than that of the connecting end 530, which can effectively avoid the brush cylinder body 51 and facilitate the effective use of the width of the product in the transverse direction, while increasing the resistance to deformation of the detachable component body 531 when it is operated under a large torsion. The transverse width of the operating end 532 is greater than that of the detachable component body 531, that is, the operating end 532 is provided with an extension 533 in the transverse direction, which makes the operating end 532 greater than the width of the detachable component body 531 in the transverse direction, thereby facilitating operation during operation. The brush cylinder support 1 is provided with an empty space 11 for accommodating the detachable component 53.

[0062] Referring to Figure 2 , Figure 11 In some embodiments, a step 535 is arranged between the connecting end 530 and the detachable component body 531 as needed, which can effectively increase the connection strength between the connecting end 530 and the detachable component body 531. The step surface on the step 535 is matched with the corresponding supporting surface (not shown in the figure) of the brush cylinder support 1 when the detachable component 53 is in the locked state, which can improve the stability of the brush cylinder 5 during high-speed rotation.

[0063] Referring to Figure 5 , Figure 7 ,Figure 9 、 Figure 11 In some embodiments, the connecting end 530 comprises a pair of crescent-shaped clamping structures arranged in the area where the dismounting body 531 and the protruding shaft (not shown in the figure) of one end of the brush roller 5 are engaged with each other, the roots of the clamping structures are integrated with the dismounting body 531, and the clamping structures extend to a certain width in the axial direction of the brush roller 5, so as to provide sufficient clamping force while tightly clamping the protruding shaft of one end of the brush roller 5, transmitting the force to the dismounting body 531, and then transmitting the force to the corresponding support surface of the brush roller support 1 through the stepped surface on the step 535 of the dismounting body 531 when the dismounting member 53 is in the locked state, so as to improve the stability of the brush roller 5 in high-speed rotation.

[0064] Referring to Figure 1 、 Figure 3 、 Figure 4 、 Figure 6 In some embodiments, when in use, the brush roller 5 is connected to the transmission mechanism 4 at one end, and the other end is fixed to the brush roller support 1 through the dismounting member 53, so as to realize the working of the brush roller 5. When dismounting is needed, the user needs to buckle the index finger into the avoidance position 11, and then use the thumb to clamp the operating end 532 and turn the dismounting member 53 outward, so as to overcome the coupling force between the dismounting member 53 and the brush roller support 1 (which can be the maximum elastic pressure of the clamping groove 13 between the clamping grooves 534, or the maximum attractive force between the magnetic body 12 and the magnetic body 536), and then the user can easily turn the locked position of the dismounting member 53, and then dismount the brush roller 5 from the brush roller support 1 at one end, and then pull out the brush roller 5 along the length direction. The advantage of taking out the brush roller is that the entire brush roller assembly does not need to be separated from the cleaning appliance, which is convenient for operation. At the same time, since the transverse width of the dismounting body 531 of the dismounting member 53 is greater than that of the connecting end 530, the dismounting member 53 can provide greater strength, avoid irreversible deformation caused by force during locking or dismounting, and avoid increasing the space in the structure, so as to leave more effective space for the brush roller.

[0065] The beneficial effects of the present application are: on the one hand, since the coupling structure is arranged between the brush roller 5 and the brush roller support 1, the two can be separated, so that when the user needs to remove the brush roller 5, he can not directly touch the brush roller 5 with his hand, but only needs to directly grab the detachable end 53 of the detachable brush roller 5 with his hand and pull it outward to pull out the entire detachable brush roller 5, then continue to hold the detachable end 53 with his hand and put the entire brush roller 5 under the faucet for flushing, so that the brush roller 5 can be flushed clean without directly touching it with the hand, which is convenient and not easy to dirty the hand. On the other hand, the side-pullable detachable brush roller assembly can be pulled out along the length direction of the brush roller support 1 after the brush roller 5 is unlocked from one end of the brush roller support 1 through the detachable member 53. In the prior art, the upper cover of the brush roller assembly also serves as the upper cover plate of the garbage box, and when the garbage accumulated in the garbage box needs to be poured out, the brush roller assembly needs to be removed first and then the garbage box can be taken out from bottom to top. The present application has the advantage that the brush roller does not need to be separated from the cleaning appliance, but only needs to be pulled out sideways, and since the frequency of pouring out the garbage box is obviously more than the frequency of cleaning the brush roller, the user's negative emotions caused by frequently opening the upper cover of the brush roller assembly in the prior art can be overcome.

[0066] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present application. The above-described embodiments are only used to illustrate the technical solutions of the present application, and not to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent replacements to some technical features, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.

When disassembly is needed, the user needs to buckle the index finger into the empty space and then use the thumb to clamp the operating end and turn the detachable component outward. When the coupling force between the detachable component and the brush roller support is overcome, the locking position of the detachable component is opened.
