Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly to a cutting device and a cleaning device. Background Art

[0002] A floor washer is a common household cleaning device, which usually includes a dust collector, a filter assembly, a water spraying assembly and a vacuum source. Through the suction of the vacuum source and the filtering effect of the filter assembly, garbage such as dust or debris is collected in the dust collector.

[0003] In order to improve the cleaning efficiency, a suction port is usually provided at the bottom of the vacuum cleaner, a rotating brush is provided at the suction port, and a water spraying port is provided beside the rotating brush. However, during the operation of the floor washer, the rotating brush in contact with the wet ground is very easy to entangle with filamentous substances such as hair, especially the rotating brush of the electric floor brush. Since the rotating brush moves in a rotating and rolling motion during the working process, it is more likely to entangle with filamentous substances such as hair. Excessive entanglement of the filamentous substances not only affects the sewage suction effect, but may even jam the roller, resulting in the blocking of the rotating brush motor and eventually damaging the transmission mechanism, affecting the service life of the whole machine.

[0004] Therefore, users often need to open the rotating brush cover or turn the whole floor brush over after the floor washer stops to clean the filamentous substances entangled on the rotating brush. The treatment of these filamentous substances is very troublesome and needs to be removed one by one manually. Especially, it is difficult to clean the hair filaments embedded in the rotating brush. Summary of the Invention

Detailed implementation mode

[0077] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0078] The following combines Figures 1 to 12 , and describes the embodiments of the present invention.

[0079] According to an embodiment of the present invention, on the one hand, a cutting device for a cleaning device is provided, including: a first driving component adapted to drive the rotating brush 1 of the cleaning device to rotate; a first transmission mechanism connected to the first driving component; a winding device 3 connected to the first transmission mechanism, adapted to be arranged on the rotating brush 1 and wind the attachments on the rotating brush 1 when the rotating brush 1 rotates, and have a stopped state driven by the first transmission mechanism; a second driving component; a cutting tool device 8 connected to the second driving component, adapted to be relatively arranged with the winding device 3 when the winding device 3 is in the stopped state, and cut the attachments on the winding device 3 driven by the second driving component. By arranging the winding device 3 on the rotating brush 1, when the first driving component drives the rotating brush 1 to rotate, the attachments such as hair and other filaments on the rotating brush 1 can be transferred to the winding device 3. By arranging the second driving component and the cutting tool device 8, when the winding device 3 is in the stopped state, it can be relatively arranged with the cutting tool device 8, and the second driving component drives the cutting tool device 8 to cut the hair on the winding device 3. The cut hair becomes broken hair and is easily cleaned, preventing the hair from winding around the rotating brush 1 and being difficult to clean, which affects the user experience.

[0080] As shown Figure 1 in the figure, the cutting device in this embodiment includes a cover body 11 and a base 12. A cutting tool device 8 and a winding device 3 are provided on the cover body 11, and a first driving assembly and a rolling brush 1 are provided on the base 12.

[0081] The cutting device in this embodiment includes a stopping device. One end of the stopping device is fixedly connected to the cover body 11. The stopping device is connected to the first transmission mechanism. The other end of the stopping device is adapted to move relative to the winding device 3 under the drive of the first transmission mechanism, and when the winding device 3 is in a stopped state, the stopping device is fixed on the winding device 3. By providing the stopping device, it can cooperate with the winding device 3 to realize the stop of the winding device 3, so that the winding device 3 can be relatively stably maintained in the stopped state when it is in the stopped state. As an alternative embodiment, it may also be that the stopping device is not provided, but the stop of the winding device 3 is realized by controlling the stop of the first driving assembly, and the movement of the winding device 3 is realized by controlling the start of the first driving assembly.

[0082] Specifically, the stopping device is a stopping rod 2; a stopping groove 3011 is provided on the winding device 3. When the winding device 3 is in a stopped state, the stopping rod 2 is inserted into the stopping groove 3011. By providing the stopping groove 3011 on the winding device 3 and setting the stopping device as the stopping rod 2, the stop of the winding device 3 is realized when the stopping rod 2 is inserted into the stopping groove 3011, and the structure is relatively simple. As an alternative embodiment, it may also be that the stopping device is a stopping groove and a stopping rod is provided on the winding device 3.

[0083] As shown Figure 3 in the figure, the winding device 3 includes: two side covers 301, and a stopping groove 3011 is provided on the side cover 301; a winding shaft 302 is arranged between the two side covers 301, and both ends of the winding shaft 302 respectively pass through the side cover 301 and are fixedly connected to the first transmission mechanism; a winding rod 303 is arranged outside the winding shaft 302 and is adapted to wind the hair on the rolling brush 1. By setting the winding device 3 in the form including the winding shaft 302, the winding rod 303 and the two side covers 301, the structure of the winding device 3 is made more compact.

[0084] As shown Figure 4 in the figure, the side cover 301 includes a side cover body. A central hole 3014 for the end of the winding shaft 302 to pass through is provided in the middle of the side cover body. A moving area 3012 is provided between the side cover body and the central hole 3014. The moving area 3012 is recessed inward relative to the end of the side cover body. The other end of the stopping rod 2 can slide along the moving area 3012 under the drive of the first transmission mechanism. A stopping groove 3011 is provided on the moving area 3012. When the stopping rod 2 slides to the stopping groove 3011, the winding device 3 stops rotating.

[0085] To ensure that the stop lever 2 is always in contact with the moving area 3012 of the side cover 301, the cutting device includes a spring 6. The spring 6 is disposed outside the stop lever 2 and is fixedly connected to the cover body 11 at one end.

[0086] To facilitate hair cutting, the winding device 3 includes a cutting housing 304. The cutting housing 304 is disposed outside the winding rod 303. A cutting groove 3041 is provided on the cutting housing 304. When the winding device 3 is in a stopped state, the cutter device 8 is disposed opposite to the cutting groove 3041. By providing the cutting housing 304 outside the winding rod 303 and the cutting groove 3041 on the cutting housing 304, when the winding device 3 is in a stopped state, the cutter device 8 can be disposed opposite to the cutting groove 3041, facilitating the shearing of the hair on the winding device 3 through the cutting groove 3041.

[0087] Among them, the part of the winding shaft 302 that cooperates with the winding rod 303 has a square structure. A square hole is provided in the middle of the winding rod 303. The square hole of the winding rod 303 is sleeved outside the square structure of the winding shaft 302 to achieve the assembly connection between the winding rod 303 and the winding shaft 302. As Figure 3 and Figure 5 shown, a plurality of grooves 3031 are further provided on the circumferential outer side of the winding rod 303. A plurality of cutting housings 304 are inserted into the grooves 3031. An arc-shaped rib 3042 is provided at the end of the cutting housing 304. A plurality of arc-shaped grooves 3013 are provided on the side of the side cover 301 opposite to the moving area 3012. The arc-shaped rib 3042 of the cutting housing 304 is inserted into the arc-shaped groove 3013 of the side cover 301 to achieve the assembly connection between the cutting housing 304 and the side cover 301.

[0088] In this embodiment, the size of the winding rod 303 is smaller than that of the roller brush 1 and has adhesiveness. By setting the size of the winding rod 303 to be smaller than that of the roller brush 1 and having adhesiveness, the winding rod 303 can achieve high rotational speed and high adhesiveness, drive the hair to wind quickly, thereby stripping the hair on the roller brush 1 and transferring the hair on the roller brush 1 to the winding rod 303.

[0089] Specifically, both the winding rod 303 and the roller brush 1 have a cylindrical structure. The end diameter of the winding rod 303 is smaller than the end diameter of the roller brush 1, and the frictional force of the winding rod 303 is greater than that of the roller brush 1. The material of the winding rod 303 is a soft material, specifically rubber or silica gel, which is not limited here. Since the surface of the roller brush 1 is a fluffy flannelette and the surface of the winding rod 303 is a material such as rubber or silica gel with a large frictional force and certain adhesiveness, when the roller brush 1 rotates, the frictional force drives the winding rod 303 to rotate, and the hair on the roller brush 1 is adhered to the winding rod 303.

[0090] The initial position of the winding rod 303 is in interference fit with the surface flannelette of the roller brush 1 and is located at the upper left corner of the roller brush 1.

[0091] As shown Figures 6 to 8 in FIG. 2, the cutter device 8 includes: a fixed cutter assembly; a moving cutter assembly connected to the second driving assembly and adapted to move relative to the fixed cutter assembly under the drive of the second driving assembly. By configuring the cutter device 8 to include a fixed cutter assembly and a moving cutter assembly, and driving the moving cutter assembly to move relative to the fixed cutter assembly by the second driving assembly, the cutting of hair is achieved.

[0092] Among them, the fixed cutter assembly includes: a fixing plate 802 and a fixed cutter 801, and the fixed cutter 801 and the fixing plate 802 are fixedly connected by screws. The moving cutter assembly includes: a moving cutter 803; a moving cutter pressing plate 804 fixedly connected to the moving cutter 803, and a first fixing portion 8041 is provided on the moving cutter pressing plate 804; a moving cutter driving portion connected to the second driving assembly, and a second fixing portion cooperating with the first fixing portion 8041 is provided on the moving cutter driving portion, and is adapted to drive the moving cutter pressing plate 804 to move relative to the fixed cutter 801 assembly under the drive of the second driving assembly. That is, as Figure 6 shown in FIG. 3, the moving cutter 803 moves relative to the fixed cutter 801 in the left - right direction. By providing the moving cutter pressing plate 804, it is prevented that the moving cutter 803 moves away from the fixed cutter 801 assembly during the movement. If the moving cutter 803 and the fixed cutter 801 are separated and not in contact, the hair cannot be sheared, which ensures the cutting effect and is convenient for connecting with the moving cutter driving portion to realize the movement of the moving cutter 803.

[0093] Specifically, the fixing plate 802 and the fixed cutter 801 are fixedly connected by screws, and the moving cutter pressing plate 804 and the moving cutter 803 are fixedly connected by screws 809. The fixing plate 802 is disposed at the lowermost position, the moving cutter pressing plate 804 is disposed at the uppermost position, and the fixed cutter 801 and the moving cutter 803 are disposed between the fixing plate 802 and the moving cutter pressing plate 804.

[0094] The second driving assembly in this embodiment includes: a second transmission mechanism connected to the first driving assembly; a fifth transmission mechanism connected to the second transmission mechanism, and the moving cutter driving portion is fixedly connected to the fifth transmission mechanism, and is adapted to drive the fifth transmission mechanism by the second transmission mechanism and then drive the moving cutter driving portion to move under the drive of the first driving assembly. By configuring the second driving assembly as a second transmission mechanism and a fifth transmission mechanism, the entire cutting device can use only one first driving assembly as the power source to realize the movement of the brush roller 1, the winding device 3 and the cutter device 8, so that the overall structure has fewer components and is simpler and more reliable. As an alternative embodiment, it can also be that the second driving assembly and the first driving assembly are both independent power sources, and the second driving assembly includes a motor, a gear and a rack to realize the movement of the moving cutter 803 relative to the fixed cutter 801.

[0095] As Figure 7As shown, the moving knife driving part includes: a moving knife fixed shaft 805, which is fixedly connected to the fifth transmission mechanism; a conversion device 806, which is arranged on the moving knife fixed shaft 805. A second fixing part is arranged on the conversion device 806, and is adapted to convert the rotation of the fifth transmission mechanism into the translational movement of the moving knife 803 relative to the fixed knife assembly.

[0096] Among them, the first fixing part 8041 is a fixing column. The conversion device 806 includes: a conversion body, which is fixedly connected to the outside of the moving knife fixed shaft 805; a conversion ring groove, which is arranged in a ring structure outside the conversion body. The second fixing part is a groove part formed by the conversion ring groove extending along the axial direction of the moving knife fixed shaft 805, and is adapted to enable the fixing column to translate axially along the conversion ring groove when the fifth transmission mechanism drives the moving knife fixed shaft 805 to rotate. Specifically, the conversion ring groove is a misaligned ring groove similar to an S shape.

[0097] As a transformable implementation manner, it can also be that the moving knife driving part is a guide rail, which cooperates with a motor, a gear and a rack to realize the movement of the moving knife 803 relative to the fixed knife 801.

[0098] As Figure 7 shown, the fifth transmission mechanism is a transmission gear 9, and the cutting device includes a bearing 807 and a circlip 808. The moving knife fixed shaft 805 is a square column, and a square hole is provided in the center of the conversion device 806. The conversion device 806 and the moving knife fixed shaft 805 are fixed by the cooperation of the square column and the square hole. After the conversion device 806 and the moving knife fixed shaft 805 are assembled, the bearing 807 is sleeved on the moving knife fixed shaft 805 and fixed at both ends of the conversion device 806, and the transmission gear 9 is inserted into one end of the moving knife fixed shaft 805. Finally, the circlip 808 is snapped into the end of the moving knife fixed shaft 805 to play a limiting role.

[0099] In this embodiment, the second transmission mechanism is connected to the first transmission mechanism, and under the drive of the first drive assembly, the second transmission mechanism drives the first transmission mechanism to rotate. By connecting the first transmission mechanism and the second transmission mechanism, under the drive of the first drive assembly, the second transmission mechanism can drive the first transmission mechanism to rotate, without the need to additionally set up a drive mechanism, reducing the setting of components and making the overall structure simpler. As a transformable implementation manner, it can also be that the first transmission mechanism and the second transmission mechanism are independently arranged and are respectively driven by a drive mechanism.

[0100] The first drive assembly in this embodiment includes: a drive mechanism; a third transmission mechanism, which is connected to the second transmission mechanism; a fourth transmission mechanism, one end of which is connected to the drive mechanism and the other end of which is connected to the third transmission mechanism.

[0101] Specifically, the driving mechanism is a motor; the fourth transmission mechanism is a belt 4; the third transmission mechanism is a second gear set 5, and the second gear set 5 includes two layers of gears arranged inside and outside, namely a second gear and a third gear. The second gear is a large inner gear 501, and the third gear is a small outer gear 502.

[0102] The first transmission mechanism is a lifting cam 10. An arc-shaped long groove 1001 is provided on the lifting cam 10. A stop rod 2 is inserted into the arc-shaped long groove 1001. When the coiling device 3 is lifted to a stop state, the stop rod 2 fixes the coiling device 3. A mounting hole 1003 is provided near the arc-shaped long groove 1001 on the lifting cam 10. The end of the coiling shaft 302 passes through the central hole 3014 of the side cover 301 and is inserted into the mounting hole 1003. By setting the first transmission mechanism as the lifting cam 10, it is convenient to cooperate and connect with the coiling device 3 to realize the lifting and stopping of the coiling device 3.

[0103] The second transmission mechanism is a first gear set. The first gear set includes a first gear and a transmission cam 7 provided outside the first gear. The first gear is connected to the fifth transmission mechanism, and the transmission cam 7 is connected to the first transmission mechanism. By setting the second transmission mechanism as the cooperation form of the first gear and the transmission cam 7, it is possible to simultaneously connect with the fifth transmission mechanism and the first transmission mechanism using one transmission mechanism, making the structure simpler and more compact.

[0104] As Figure 9 and Figure 10 shown, one end of the belt 4 is connected to the motor, and the other end of the belt 4 is sleeved on the large inner gear 501 of the second gear set 5. The large inner gear 501 fits with the belt 4 to drive the rotary brush 1 to rotate, and the small outer gear 502 fits with the first gear set. The first gear set includes a first gear provided inside and a transmission cam 7 provided outside the first gear. The first gear functions to fit with the second gear set 5 and the transmission teeth 9 connected to the cutter device 8, enabling the moving knife fixed shaft 805 and the conversion device 806 connected to the transmission teeth 9 to rotate, thereby driving the moving knife pressing plate 804 and the moving knife 803 inserted into the conversion device 806 to perform axial reciprocating motion.

[0105] The lifting cam 10 is fixed between the fixed frame of the fixed motor and the side wall of the cover 11 through the lifting cam fixing shaft 1002, and the transmission cam 7 is fixed between the fixed frame of the fixed motor and the side wall of the cover 11 through the transmission cam fixing shaft 701. The transmission cam 7 is fitted and connected with the lifting cam 10. Since the transmission cam 7 has a D-shaped structure, with a part protruding and a part flat, that is, the transmission cam 7 includes a protruding structure and a flat structure. When the transmission cam 7 rotates to the protruding structure contacting the lifting cam 10, the lifting cam 10 swings around its fixed shaft, and at the same time drives the coiling device 3 fixed on the lifting cam 10 to lift synchronously. At this time, as the coiling rod 303 swings, when the stop groove 3011 on the side cover 301 of the coiling rod 303 swings to the highest limit point, the stop rod 2 fixed on the cover 11 falls into the stop groove 3011, causing the coiling rod 303 to stop rotating, and the cutting housing 304 on the coiling device 3 is just aligned with the cutter head of the cutter device 8, so that the cutter head enters the cutting groove 3041, and the moving cutter 803 that has been reciprocating cuts the hair, making it break, and then through the rotation of the first gear set, the coiling rod 303 is pressed down to rub against the roller brush 1 to realize the downward movement of the hair, and finally it is sucked away by the suction port of the cleaning device.

[0106] Since when the coiling device 3 stops rotating, the stop rod 2 is inserted into the stop groove 3011, with the rotation of the first gear set, in order to facilitate the withdrawal of the stop rod 2 from the stop groove 3011, a guiding inclined surface can be provided in the stop groove 3011 to facilitate the withdrawal of the stop rod 2 from the stop groove 3011 when the coiling device 3 moves downward.

[0107] Initially, the stop rod 2 passes through the arc-shaped long groove 1001 of the lifting cam 10 and is located at the highest point of the arc-shaped long groove 1001 of the lifting cam 10. The end of the stop rod 2 passes through the arc-shaped long groove 1001 and abuts against the side cover 301 of the coiling device 3, that is, the end of the stop rod 2 is located within the moving area 3012 of the side cover 301. As the lifting cam 10 swings, it drives the coiling device 3 to lift together, then the stop groove 3011 of the side cover 301 enters the range of the arc-shaped long groove 1001 of the lifting cam 10, and the stop rod 2 is inserted into the stop groove 3011 of the side cover 301, and the coiling device 3 stops rotating. As the transmission cam 7 continues to rotate, when it rotates to the flat structure of the transmission cam 7 contacting the lifting cam 10, it drives the lifting cam 10 to descend, and the coiling device 3 is pressed down to contact the roller brush 1, and this cyclic motion is continuously performed to realize the lifting and pressing down of the coiling device 3.

[0108] In this embodiment, the cutting device drives the coiling rod 303 to rotate by rubbing the coiling rod 303 with the roller brush 1, transfers the hair to the coiling rod 303, the coiling device 3 is lifted, the moving cutter 803 of the cutter device 8 moves horizontally to cut the hair, the coiling rod 303 is pressed down, the coiling device 3 resets, and the hair is transferred back to the roller brush 1 and brought to the suction port of the cleaning device, so that the hair is sucked away.

[0109] In this embodiment, the cutting device uses a take-up rod 303 to transfer the hair on the rotary brush 1. After lifting and disengaging from the rotary brush 1 and stopping rotating, the moving knife 803 performs hair cutting through axial movement. The fluffy hair is driven and thrown out and sucked away by the rotary brush 1 during the downward pressing process of the take-up rod 303. It can realize that the rotary brush 1 drives the take-up device 3 and the moving knife 803 device to work all the time, and at the same time, the take-up device 3 is lifted and quickly stops rotating, realizing the transfer and fluffing of the hair, being easy to cut, and being less likely to wind around the rotary brush 1, so as to realize the easier removal of the wound hair.

[0110] According to an embodiment of the present invention, on the other hand, a cleaning device is also provided, including: the above-mentioned cutting device; a rotary brush 1, connected to a first driving assembly, and a take-up device 3 is provided on the rotary brush 1.

[0111] As Figure 12 shown, the cleaning device in this embodiment is a floor washer. As an alternative embodiment, the cleaning device can also be a cleaning machine or a mopping and washing integrated machine.

[0112] Although the 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 the appended claims.
