Description

Technical Field

[0001] The invention relates to the field of household appliances, in particular to a tangled object cleaning device. Background Art

[0002] At present, intelligence has become the development trend of the home appliance industry. With the development of information technology, more and more smart home appliances are gradually entering our lives. The sweeping robot is a kind of smart home appliance. It can automatically complete the floor cleaning work in the room with a certain degree of artificial intelligence, reducing the intensity of manual labor and providing convenience for modern life.

[0003] When the robot vacuum cleaner is in operation, the cleaning brush is driven by the rotating shaft to gather dust on the ground. During the rotation of the cleaning brush, hair, thin wires and other entanglements on the ground are easily entangled on the rotating shaft. When there are too many entanglements on the rotating shaft, the rotation rate of the cleaning brush will be affected, thereby reducing the cleaning effect and efficiency of the robot vacuum cleaner. In addition, the entanglements on the rotating shaft are particularly difficult to clean.

[0004] Patent No. 201920214693.2 is named a cleaning component and a sweeping robot, including: a fixed frame, a rotating shaft rotatably supported on the fixed frame, and a cleaning brush sleeved on the rotating shaft, the cleaning component also includes at least one winding removal device, the winding removal device includes a blade and a blade mounting seat, the blade mounting seat is arranged on the fixed frame, the blade is retractably mounted on the blade mounting seat, and the blade in the extended state faces the portion of the rotating shaft exposed to the cleaning brush and can contact the winding on the portion. Through the cleaning component provided by the utility model, the sweeping robot can automatically cut off the windings wound on the rotating shaft during operation, and the cut windings are sucked into the dust box by the rotating shaft under the suction of the dust suction motor, which is convenient for users to clean the sweeping robot, increase the rotation speed of the rotating shaft, speed up the cleaning efficiency, and improve the cleaning effect of the sweeping robot.

[0005] However, after using this cleaning assembly, it was found that the entangled objects could not be completely removed, and only the entangled objects around the cleaning brush could be removed. That is, because the blade and the brush strip are not in close contact, the hair and thin wires entangled and attached to the brush strip are not easy to be cut off. Summary of the invention

[0006] In order to solve the above problems, the present invention provides a tangled object cleaning device, the purpose of which is to solve the problem of poor efficiency of removing tangled objects in the cleaning assembly in the prior art.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a tangled material cleaning device, having at least one window corresponding to a roller brush, a shearing portion that moves along the axial direction of the roller brush is provided in the window, and the shearing portion is formed by splicing at least one group of components with teeth on the side edges, wherein the components are a first component and a second component, and at least one of the first component and the second component performs a reciprocating motion to cut off the tangled material.

[0008] The beneficial effect of the present invention is to improve the structure of the shearing part, which is composed of two parts, and the part is divided into a second part and a first part to form shearing. The shearing part reciprocates along the axial direction of the roller brush and approaches the outer surface of the roller brush to achieve shearing of the winding object.

DETAILED DESCRIPTION

[0020] A sweeping robot, also known as an automatic sweeper, smart vacuum cleaner, robot vacuum cleaner, etc., is a type of smart home appliance that can automatically clean the floor in the room with a certain degree of artificial intelligence. It generally uses brushing and vacuuming to absorb debris on the floor into its own garbage collection box, thereby completing the function of floor cleaning. Generally speaking, robots that complete sweeping, vacuuming, and mopping are also collectively classified as sweeping robots.

[0021] Just as the role played by sweeping robots is enormous, the problems they face have also emerged as their widespread use has increased, especially the roller brushes used to remove entangled hair, thin wires, etc., which often cause great trouble to users because they cannot remove the entangled objects.

[0022] Although there are cleaning components on the market that can cut off hair, thin wires, etc. to achieve cleaning purposes, such as patent number 201920214693.2, which is named a cleaning component and a sweeping robot, this matching cleaning component and sweeping robot cannot completely eradicate entanglements. After long-term use, more entanglements that cannot be removed will accumulate, which is unbearable for most users.

[0023] Therefore, in order to make this roller brush more commonly used, Figure 8 and Fig.10 As shown, the present invention provides a entanglement cleaning device, which has at least one window 1 corresponding to a roller brush, and a shearing portion that moves along the axial direction of the roller brush is provided in the window 1, and the shearing portion is composed of a group of components with teeth 6 on the side edges, wherein the components are a first component 2 and a second component 3, respectively, and at least one of the first component 2 and the second component 3 performs a reciprocating motion to cut off the entanglement;

[0024] It should be noted that, according to the above solution, when the sweeping robot using the roller brush removes entanglements, it is not necessary to process the entanglements in a traditional manner, that is, the entanglements can be removed without rotating the cleaning brush;

[0025] Therefore, when the sweeping robot moves to the winding cleaning device and the roller brush corresponds to the window 1, the shearing part can move along the axial direction of the roller brush and shear the winding, and the shearing process is achieved by using two parts with teeth 6 (such as Figure 5 As shown), specifically, a staggered manner, such as one side is stationary and the other side is movable or both are relatively movable, combining two teeth 6 on the component to achieve cutting of the winding;

[0026] For example:

[0027] 1. The first component 2 is movable and the second component 3 is stationary, and the teeth 6 of the first component 2 and the teeth 6 of the second component 3 are fitted together to cut off the winding, which is also an embodiment of the attached drawings of the present invention;

[0028] 2. The second component 3 moves while the first component 2 is stationary, and the teeth 6 of the first component 2 fit with the teeth 6 of the second component 3 to cut off the winding. The drawings of the present invention do not show an example of the driving motor 5 driving the second component 3. The same structure as that for driving the first component 2 can be used, or other structures can be used as long as the above functions can be achieved.

[0029] 3. The first component 2 and the second component 3 simultaneously make reciprocating motions in opposite directions to form a cutting mode, which is also for the purpose of cutting the winding material.

[0030] like Fig.10 In this specific embodiment, the arrangement of the multiple teeth 6 is perpendicular to the axial direction of the roller brush, and the first component 2 and / or the second component 3 moves in an up-and-down manner to form shearing. In this operation mode, the teeth 6 can be closer to the brush strip 20, and the cutting space is wider. However, according to needs, the arrangement of the multiple teeth 6 is not perpendicular to the axial direction of the roller brush, as long as the purpose of cutting the entangled material can be achieved.

[0031] like Figure 2 The shearing part includes a driving motor 5, the purpose of the driving motor 5 is to rotate the rotating member 4 on the motor shaft, and drive the eccentric shaft to rotate, thereby driving the first component 2 or the second component 3 to reciprocate to form a shearing action;

[0032] The above technical solution is to provide a regular trajectory so that the first component 2 can follow the rotating part to make a reciprocating motion accordingly, thereby achieving the purpose of cutting the winding. Of course, this motor driving method is also applicable to the method in which the first component 2 and the second component 3 are both movable and rotating.

[0033] It should be noted that the arrangement direction of the multiple teeth on the shearing portion can be perpendicular to the axial direction of the roller brush. Based on this design, even if the top of the first component 2 contacts the surface of the roller brush, the teeth 6 will not puncture the surface of the roller brush. Compared with a cleaning component and a sweeping robot in the prior art, when dealing with entangled objects, there is no need to consider the distance between the cleaning brush and the blade.

[0034] In a preferred mode of this specific embodiment, the roller brush includes a plurality of brush strips 20 and a cleaning groove 19 distributed between two adjacent brush strips 20. Since dust is negatively charged, hair and string will be stuck between the two brush strips 20 due to dust. Therefore, on the basis of designing the cleaning groove 19, when the first component 2 penetrates into the cleaning groove 19, the entangled objects accumulated in the area adjacent to the cleaning groove 19 can be cut off. That is to say, limited by the structure of the brush strips 20, the area of ​​the roller brush that can be covered by hair and string belongs to the activity range of the component.

[0035] Corresponding to the first component 2, an elastic positioning component 16 for fixing the first component 2 should also be provided, which is arranged on the moving component 2 in a manner opposite to the teeth 6 on the first component 2, and the first component 2 is pressed on the second component 3 by the elastic positioning component 16 close to the teeth 3. Therefore, the elastic positioning component 16 has at least one end, and this end is fixed to the first component 2;

[0036] The above technical solution is adopted considering that the teeth 6 on the first component 2 are consumables, and therefore the difficulty of replacing the first component 2 also needs to be considered. In this regard, the elastic positioning component 16 can be moved within a certain space. For example, applying external force to the elastic positioning component 16 will cause the first component 2 to flip over.

[0037] In this specific embodiment, a component positioning seat 7 is also included, and the first component 2 and the second component 3 are mounted on the component positioning seat 7. At the same time, the elastic positioning component 16 is a torsion spring, and the torsion spring has a handle 1601 and a positioning portion 1602. The positioning portion 1602 is embedded in the first component 2, and the handle 1601 is arranged at a position away from the first component 2.

[0038] It should be pointed out that the handle 1601 of the torsion spring is positioned on the component positioning seat 7 by means of an axis. Therefore, as can be seen from Figures 3-4, by pressing to the right, the torsion spring flips around the axis, thereby driving the first component 2 to separate from the second component 3.

[0039] In a preferred embodiment of this invention, Figure 2 The following is an example of the rotating member 4 driving the first member 2 to move up and down. The rotating member 4 is provided with an eccentric shaft, and the first member 2 is provided with two blocking parts 8, which are respectively located above and below the eccentric shaft:

[0040] When the eccentric shaft rotates upward, it contacts the upper blocking portion 8 and drives the blocking portion 8 and the first component 2 to move upward;

[0041] When the eccentric shaft rotates downward, it contacts the blocking portion 8 below and drives the blocking portion 8 and the first component 2 to move downward, thereby achieving reciprocating motion of the first component 2 in the up and down directions to form shearing.

[0042] The amplitude of the reciprocating motion of the first component 2 in the up-and-down direction is determined by the distance between the eccentric shaft and the axis of the rotating component 4. The greater the distance, the greater the amplitude of the motion.

[0043] The reason why the shearing part can move along the axial direction of the roller brush is that the structure itself is provided with a linear track, and the active area of ​​the linear track supports the shearing part.

[0044] It should be noted that the window 1 referred to herein is provided on a base station housing 9 having a slope for supporting the sweeping robot, and therefore, the linear track for implementing the moving function is provided inside the base station housing 9;

[0045] like Figure 6 As shown, the linear track includes a sliding motor 10, a sliding table 11, a conveyor belt 12, a straight shaft 13, a follower base 15, and a follower 14 installed on the follower base 15. Both ends of the straight shaft 13 are fixed in the housing, the sliding table 11 is sleeved on the straight shaft 13, and the follower base 15 is fixed on the sliding table 11. The sliding motor 10 drags the conveyor belt to make the sliding table 11 do a reciprocating motion along the straight shaft 13.

[0046] Furthermore, the connection performance between the conveyor belt 12 and the positioning block 17 can be improved by increasing the contact surface and the friction force, such as Figure 7 As shown, a convex strip is provided on the inner periphery of the conveyor belt 12, and a positioning block 17 which can engage with the conveyor belt 12 is provided on the surface of the sliding table 11, and a strip-shaped body 1701 which abuts against the convex strip is provided on the positioning block 17; this strip-shaped body 1701 can be a triangle.

[0047] like Fig. 9 As shown, the present invention also provides a floor cleaning system, including a base station and a sweeping robot paired with each other, the sweeping robot including a housing base 18, a driving wheel 21 and a roller brush, the roller brush and the driving wheel 21 are arranged on the housing base 18 of the sweeping robot, and the base station housing 9 is provided with the entanglement cleaning device of the present invention;

[0048] It should be noted that the surface of the base station housing 9 is provided with two driving wheel grooves 22. When the cleaning robot moves in the direction of the arrow (such as Figure 8 When the base station housing 9 is moved to the base station housing 9, the driving wheel 21 will enter the driving wheel groove 22, so that the roller brush will fall into the window 1, so that the subsequent winding cleaning device can handle the winding.

[0049] It should also be noted that most of the above explanations are illustrated by examples in which the first component 2 undergoes dynamic changes and the second component 3 is in a static state. In this regard, the various components or devices cited in the above examples can also be applied to other staggered cutting methods for the first component 2 and the second component 3.

[0050] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
