Claims 3 / 3 Page 4 CN 121549719 A Cleaning tray, cleaning component, cleaning device and cleaning system Technical Field

[0001] The present invention relates to the field of cleaning equipment technology, specifically to a cleaning tray, cleaning component, cleaning device and cleaning system. Background Art

[0002] With the development of technology, automatic cleaning equipment such as sweeping machines and floor scrubbers have been widely used in homes and commercial places; the goal of these devices is to achieve automated cleaning of the whole house and free up users' hands. However, the mainstream round rags and roller rags on the market have good cleaning effect for open areas, but for areas such as right angles inside walls, wall edges, and furniture edges, due to their own shape, they cannot fit tightly to the edges and corners, and there are still obvious cleaning blind spots.

[0003] In view of the above, the present invention aims to provide a cleaning tray, cleaning components, cleaning equipment and cleaning system to solve the problem that existing cleaning equipment has obvious blind spots in cleaning right angles inside walls, wall edges and furniture edges.

[0004] A first aspect of the present invention provides a cleaning disc for use in a cleaning device. The main unit of the cleaning device can drive the cleaning disc to rotate. The cleaning disc includes a cleaning disc body. The cleaning disc body is provided with at least one set of corner cleaning mechanisms. The corner cleaning mechanism includes a swing member. The swing member has a retracted position, an extended position, and an obstacle avoidance position when swinging. The swing member can swing between the retracted position and the obstacle avoidance position. The axis of swing of the swing member is perpendicular to the disc surface of the cleaning disc body. The extended position is located between the retracted position and the obstacle avoidance position. When the swing member is in the extended position, the swing member extends at least partially beyond the cleaning disc body. When the cleaning disc rotates to perform cleaning operations, the swing member can swing to the extended position under the action of an external force. When the swing member is in the extended position or between the extended position and the obstacle avoidance position, it can swing towards the obstacle avoidance position when it touches an object outside the cleaning disc body.

[0005] With this configuration, the extended swing component effectively extends the cleaning range, allowing it to reach areas such as right angles inside walls, wall edges, and furniture edges that the main cleaning tray cannot cover, thus solving the problem of blind spots in cleaning.

[0006] Furthermore, when the extended swing component collides with an obstacle, it can swing towards the obstacle avoidance position to buffer and avoid damage to the swing component, furniture, walls, etc.

[0007] Preferably, it also includes a locking trigger mechanism;The locking trigger mechanism is used to lock the swing member in the retracted position, and the locking trigger mechanism can be unlocked when triggered. After the locking trigger mechanism is unlocked, the swing member can swing towards the extended position.

[0008] With this configuration, the swing member can be locked in the retracted position during normal cleaning without affecting the normal cleaning work. When an obstacle is touched, the swing member is unlocked to swing and extend, cleaning areas such as corners, edges, and obstacle edges.

[0009] Preferably, the locking triggering mechanism includes a slide rod and a first elastic element, the slide rod being slidably mounted on the cleaning tray body; The slide rod has a locking position and an unlocking position, the locking position being used to lock the swinging element in the retracted position, and the unlocking position being used to unlock the swinging element; one end of the first elastic element acts on the cleaning tray body, and the other end acts on the slide rod, so that the slide rod is held in the locking position; when the end of the slide rod away from the first elastic element is pressed, the slide rod slides to the unlocking position in the direction of compressing the first elastic element.

[0010] Preferably, the slide bar has a wedge-shaped tooth on the side near the swing member, and the swing member has a groove adapted to the wedge-shaped tooth; when the swing member is in the retracted position and the slide bar is in the locked position, the wedge-shaped tooth engages in the groove, locking the swing member in the retracted position; when the end of the slide bar away from the first elastic member is pressed, the slide bar slides in the direction of compressing the first elastic member to the unlocked position, at which time the wedge-shaped tooth disengages from the groove, and the swing member is unlocked.

[0011] Preferably, the wedge-shaped tooth faces the end of the slide bar that is pressed.

[0012] With this configuration, the swing member can be stably and reliably locked in the retracted position by the cooperation of the wedge-shaped tooth and the groove, and the swing member can be unlocked by sliding the slide bar when it is pressed. During cleaning operations, the swing member can be automatically unlocked by the collision between the slide bar and an obstacle.

[0013] Preferably, the slide bar is provided with a magnet, and the swing member is provided with an adsorption point, which can be attracted by the magnet; when the swing member is in the closed position and the slide bar is in the locked position, the magnet and the adsorption point are aligned, and the adsorption point is attracted by the magnet, locking the swing member in the closed position; when the end of the slide bar away from the first elastic member is pressed, the slide bar slides in the direction of compressing the first elastic member to the unlocked position, at which time the magnet and the adsorption point are misaligned, and the swing member is unlocked.

[0014] With this configuration, the swing member is locked in the closed position by magnetic attraction, which, compared with mechanical locking structures such as wedge teeth, can reduce the resistance and abnormal noise during locking, and reduce the wear of the locking structure.

[0015] Preferably, the locking trigger mechanism further includes a guide member disposed on the cleaning tray body, and the slide rod slides in cooperation with the guide member to achieve sliding installation of the slide rod on the cleaning tray body.

[0016] This configuration enables the slide rod to slide precisely and stably along a preset path.

[0017] Preferably, the locking trigger mechanism includes an electromagnet and a control switch. The control switch controls the energization and de-energization of the electromagnet. When the control switch is in a normally closed state, it performs a de-energization action when an obstacle is detected or touched, and then returns to the normally closed state. The electromagnet is fixedly installed on the cleaning tray body, and the swing member is at least partially made of magnetic material. When the swing member is in the retracted position, it can be attracted by the energized electromagnet to lock the swing member in the retracted position. When the electromagnet is de-energized, the swing member can swing towards the extended position.

[0018] This configuration simplifies the structure of the locking trigger mechanism, and makes the electromagnet adsorption control easier and reduces the accuracy requirements for the swing member's movement.

[0019] Preferably, the corner cleaning mechanism further includes a second elastic element, one end of which acts on the cleaning disc body and the other end of which acts on the swinging element, causing the swinging element to tend to swing towards the extended position. The extended position refers to the position of the swinging element when the second elastic element is in its natural state.

[0020] Preferably, the second elastic element is a torsion spring; or, the second elastic element is a compression spring.

[0021] With this configuration, the second elastic element can provide a stable driving force for the swinging element to swing towards the extended position, ensuring that the swinging element can swing towards the extended position after being unlocked.

[0022] Preferably, the corner cleaning mechanism further includes a mounting cavity, which is located between the two surfaces of the cleaning disc body. The swing member is installed in the mounting cavity and can swing within the mounting cavity. The mounting cavity can limit the swing member in a direction perpendicular to the surface of the cleaning disc body. The mounting cavity has an opening on the side facing the outer edge of the cleaning disc body, which allows the swing member to partially extend out of the mounting cavity beyond the cleaning disc body. The mounting cavity has a notch on the side facing the surface to be cleaned. After the second cleaning member is installed on the swing member, the second cleaning member is exposed through the notch in the mounting cavity.

[0023] With this configuration, the mounting cavity provides installation space and limitation for the swing member, allowing the swing member to swing stably along a preset path within the mounting cavity. Moreover, only the part of the swing member with the cleaning member installed is exposed, resulting in a more aesthetically pleasing and neat appearance.

[0024] Preferably, the cleaning disc body is composed of a first disc body and a second disc body, with the second disc body covering part or all of the first disc body. The mounting cavity is formed between the first disc body and the second disc body.

[0025] Preferably, the first disc body is detachably mounted on the second disc body.

[0026] With this configuration, by designing the cleaning disc body as a split structure, the processing difficulty of the mounting cavity can be reduced on the one hand, and the installation of the swinging member, the second elastic member, etc., into the mounting cavity is convenient on the other hand.

[0027] Preferably, the corner cleaning mechanism further includes a recessed groove, which is located on the side of the cleaning disc body facing the surface to be cleaned. The swinging member is hinged in the recessed groove, and the side of the recessed groove facing the outer edge of the cleaning disc body is open, so that the swinging member partially extends out of the recessed groove to the outside of the cleaning disc body.

[0028] With this configuration, the swinging member is installed at the bottom of the recessed groove, so that the side of the swinging member facing the surface to be cleaned is flush with the side of the cleaning disc body facing the surface to be cleaned, so that the cleaning members on both are in contact with the same surface to be cleaned; in addition, the installation method of the swinging member is simplified, which helps to reduce costs.

[0029] Preferably, the outer end of the swing member is provided with rounded corners and / or rubber coating. The outer end refers to the end of the swing member that extends out of the main body of the cleaning tray when the swing member is in the extended position.

[0030] The rounded corners are provided to prevent the outer end of the swing member from being too sharp and scratching the wall, furniture, etc. At the same time, the rounded corners make the outer end of the swing member contact the surface of the obstacle and move more smoothly along the surface of the obstacle, adapting to the unevenness of the obstacle surface and preventing the swing member from being blocked or stuck by the obstacle. The rubber coating is provided to buffer the collision between the swing member and the wall, furniture, etc.

[0031] Preferably, the outer end of the swing member is provided with bristles. The outer end refers to the end of the swing member that extends out of the main body of the cleaning tray when the swing member is in the extended position.

[0032] The bristles further extend the cleaning range of the swing member, and the flexible bristles are conducive to reaching into areas such as corners, edges of walls, and furniture edges.

[0033] Preferably, the end of the slide rod away from the first elastic member is provided with a rounded corner and / or rubber coating.

[0034] The rounded corner is provided to prevent the outer end of the slide rod from being too sharp and scratching the wall, furniture, etc. The rubber coating is provided to buffer the collision between the slide rod and the wall, furniture, etc.

[0035] Preferably, the surface of the cleaning tray body is provided with a plurality of drainage holes, which are used to leak cleaning water from the cleaning equipment host to the first cleaning component on the cleaning tray body and the second cleaning component on the swing component. Specification 3 / 12 pages 7 CN 121549719 A

[0036] Preferably, the first tray body is provided with a plurality of first drainage holes, and the second tray body is provided with a plurality of second drainage holes. The first drainage holes and the second drainage holes are used to leak cleaning water from the cleaning equipment host to the first cleaning component on the cleaning tray body and the second cleaning component on the swing component. The first drainage holes are circumferentially orientedThe second drain holes are spaced apart, with at least a portion of them located on the distribution path of the first drain holes.

[0037] This arrangement allows cleaning water to seep evenly onto the cleaning component.

[0038] Preferably, the angle between the retracted position and the extended position is greater than or equal to 10 degrees and less than or equal to 90 degrees.

[0039] Within this angle range, it ensures that the swing component can extend to a sufficient length while avoiding excessive swing range that would encroach on too much space of the cleaning tray body, thus significantly reducing the area of ​​the first cleaning component.

[0040] Preferably, the angle between the extended position and the obstacle avoidance position is greater than or equal to 10 degrees and less than or equal to 90 degrees.

[0041] Within this angle range, it ensures that the swing component in the extended state has sufficient space to swing towards the obstacle avoidance position when colliding with an obstacle, while avoiding excessive swing range that would encroach on too much space of the cleaning tray body, thus significantly reducing the area of ​​the first cleaning component.

[0042] Preferably, when the swing member is located in the obstacle avoidance position, the swing member is entirely located within the cleaning tray body.

[0043] With this configuration, the swing member has the ability to completely retract into the cleaning tray body without exposing the edge of the cleaning tray body when avoiding obstacles, thereby achieving complete obstacle avoidance.

[0044] Preferably, the protrusion position is arranged radially along the cleaning tray body, and the obstacle avoidance position and the retracting position are symmetrical about the protrusion position.

[0045] This is a very simple and intuitive design, which not only gives the product a symmetrical aesthetic, but also makes the design of the cleaning tray body structure, the position of the swing member, and the swing path less difficult, and the processing technology of the parts is relatively simple.

[0046] A second aspect of the present invention provides a cleaning assembly, including a first cleaning member, a second cleaning member, and a cleaning tray as described in any of the first aspects; the first cleaning member is installed on the side of the cleaning tray body facing the surface to be cleaned; the second cleaning member is installed on the side of the swing member facing the surface to be cleaned; during the cleaning process, the first cleaning member and the second cleaning member are in contact with the surface to be cleaned.

[0047] A third aspect of the present invention provides a cleaning device, including a main unit and at least one cleaning component as described in the second aspect, the cleaning component being mounted on the side of the main unit facing the surface to be cleaned, and the cleaning component being drivable to rotate.

[0048] Preferably, the cleaning component is drivable to rotate in a forward direction and in a reverse direction, the forward rotation referring to the direction of rotation of the cleaning component when performing a cleaning operation, and the reverse rotation being opposite to the direction of the forward rotation; the main unit is provided with a retraction device, and after the cleaning operation is completed, the main unit drives the cleaning component to perform the reverse rotation, during the reverse rotation, the swinging component not in the retraction position will retract with the retraction.The device contacts the oscillating component, and the retracting device pushes the oscillating component to the retracted position through contact with the oscillating component.

[0049] With this configuration, after the oscillating component extends, the cleaning range is effectively extended. The oscillating component can reach areas such as right angles inside the wall, wall edges, and furniture edges that the main body of the cleaning tray cannot cover, thus solving the problem of blind spots in cleaning. In addition, after cleaning, the main unit drives the cleaning component to rotate in the opposite direction. The oscillating component that is not in the retracted position can be pushed back to the retracted position by the retracting device, without affecting the regular cleaning work, which is conducive to achieving automation.

[0050] The fourth aspect of the present invention provides a cleaning system, including a base station and the cleaning device described in any one of the third aspects, wherein the base station has a parking compartment for the cleaning device to enter.

After the cleaning disc body 1 is installed on the main unit 14 of the cleaning equipment, the first cleaning component 12 faces away from the main unit 14 of the cleaning equipment.

[0068] The cleaning tray body 1 is provided with a set of corner cleaning mechanisms and a set of locking triggering mechanisms; the corner cleaning mechanism includes a mounting cavity 4, a swing member 2 and a second elastic member 3. The swing member 2 is generally rod-shaped, and the swing axis of the swing member 2 is perpendicular to the tray surface of the cleaning tray body 1. The mounting cavity 4 provides mounting space for the swing member 2, and the second elastic member 3 provides elastic force for the swing member 2; the side of the swing member 2 facing the surface to be cleaned is used to install the second cleaning member 13. The second cleaning member 13 is used to clean areas such as the edges and corners of obstacles that cannot be reached by the first cleaning member 12.

[0069] When the swing member 2 swings, it has a retracted position, an extended position and an obstacle avoidance position. The retracted position and the obstacle avoidance position are located at both ends of the swing range of the swing member 2, and the extended position is located between the retracted position and the obstacle avoidance position. The extended position refers to the position of the swing member 2 when the second elastic member 3 is in its natural state; when the swing member 2 is in the extended position, the outer end of the swing member 2 extends out of the mounting cavity 4 to the cleaning tray body.In addition to 1, this allows the swing member 2 to extend to the edges of obstacles or corners of walls that the first cleaning member 12 cannot reach when the cleaning disc body 1 rotates, so as to perform cleaning operations.

[0070] In this embodiment, the outer end of the swing member 2 refers to the end of the swing member 2 that extends out of the cleaning disc body 1 when the swing member 2 is in the extended position, and correspondingly, the inner end of the swing member 2 refers to the end of the swing member 2 that is located on the cleaning disc body 1 when the swing member 2 is in the extended position.

[0071] The mounting cavity 4 is formed between the two disc surfaces of the cleaning disc body 1. The mounting cavity 4 is generally flat and parallel to the disc surfaces of the cleaning disc body 1. The mounting cavity 4 can limit the swing member 2 installed therein in a direction perpendicular to the disc surfaces of the cleaning disc body 1.

[0072] The mounting cavity 4 has an opening on the side facing the outer edge of the cleaning disc body 1, and the outer end of the swing member 2 can extend out of the mounting cavity 4 to the outside of the cleaning disc body 1 through the opening; the mounting cavity 4 has a notch on the side wall facing the surface to be cleaned, and after the second cleaning member 13 is installed on the swing member 2, the second cleaning member 13 protrudes out of the mounting cavity 4 through the notch, so that the cleaning surface of the second cleaning member 13 is flush with the cleaning surface of the first cleaning member 12. The cleaning surface refers to the surface of the cleaning member that is in contact with the surface to be cleaned.

[0073] Preferably, the shape of the mounting cavity 4 and the notch is the same as the shape of the area swept by the second cleaning member 13 when the swing member 2 swings, usually a fan shape, so as to avoid interference with the second cleaning member 13 during the swing of the swing member 2.

[0074] For example, the mounting cavity 4 can be formed in the following form: the cleaning disc body 1 is composed of a first disc body 5 and a second disc body 6. The disc surface of the first disc body 5 has a groove that is consistent with the shape of the mounting cavity 4. The second disc body 6 is superimposed on the side of the first disc body 5 with the groove, and the groove opening is closed, thereby forming the mounting cavity 4. The first disc body 5 and the second disc body 6 can be fixed by screws, buckles or other structures. The split design makes it easy to install the swinging part 2, the second elastic part 3 and other components into the mounting cavity 4.

[0075] It should be noted that, as shown in Figure 3, the second disc 6 can be roughly the same in shape and size as the first disc 5, and the second disc 6 covers the entire first disc 5. In this case, the two discs are almost identical, which is convenient for manufacturing, but the structure of the original cleaning disc is significantly modified, which is suitable for the design of a completely new product; the second disc 6 can also be different in shape and size from the first disc 5. The second disc 6 only needs to cover the groove opening. The second disc 6 is similar to a cover plate that seals the groove opening. In this case, although the structures of the two discs are significantly different and need to be manufactured separately, the structure of the original cleaning disc, i.e., the first disc 5, is less modified. It is only necessary to open the groove on the original cleaning disc, which is suitable for the improvement design of existing products.

[0076] In this embodiment, the second elastic element 3 is a torsion spring. Preferably, the axis of the torsion spring coincides with the swing axis of the swinging element 2.The torsion spring can be mounted on a mounting post at the swing axis, or fixed at the swing axis with screws. One end of the torsion spring acts on the cleaning disc body 1. For example, the cleaning disc body 1 is provided with a limiting groove, and the end of the torsion spring is locked in the limiting groove to fix the end of the torsion spring. The other end of the torsion spring acts on the swing member 2. For example, the inner end of the swing member 2 is provided with a limiting groove, and the end of the torsion spring is locked in the limiting groove. Instruction manual 6 / 12 pages 10 CN 121549719 A

[0077] Referring to Figures 4 and 5, preferably, the limiting groove at the inner end of the swing member 2 is U-shaped or L-shaped. Correspondingly, the end of the swing member 2 of the torsion spring is also U-shaped or L-shaped, consistent with the limiting groove. In this way, the end of the torsion spring can also provide a limit for the swing member 2 along the length direction of the swing member 2, preventing the swing member 2 from coming out. Of course, a more common installation method for the swing member 2 is to hinge its inner end to the mounting cavity 4 through a pin, and the pin provides a limit for the swing member 2 along the length direction of the swing member 2. In addition, the swing member 2 can also be guided and limited by a structure such as a guide rod or guide groove provided in the mounting cavity 4, while preventing the swing member 2 from coming out of the mounting cavity 4.

[0078] The locking trigger mechanism includes a slide rod 7, which is slidably mounted on the cleaning tray body 1 via a guide member disposed on the cleaning tray body 1. The slide rod 7 has a locked position and an unlocked position within its sliding stroke. Exemplarily, the guide member is a groove 11 formed on the cleaning tray body 1, and the slide rod 7 is placed in the groove 11 and slides along the groove 11. In other embodiments, the guide member may also be a guide rod fixed on the cleaning tray body 1, and the slide rod 7 passes through the guide rod and slides along the guide rod.

[0079] The locking trigger mechanism also includes a first elastic member 8, which is installed at the bottom of the groove 11 and acts on the inner end of the slide rod 7. Under the action of the first elastic member 8, the slide rod 7 is held in the locked position. The outer end of the slide rod 7 in the locked position extends out of the outer edge of the cleaning tray body 1 so that when the cleaning tray rotates, the outer end of the slide rod 7 can be pressed by an obstacle, thereby causing the slide rod 7 to compress the first elastic member 8 and move towards the bottom of the groove 11, thereby causing the slide rod 7 to switch to the unlocked position.

[0080] In this embodiment, the outer end of the slide rod 7 refers to the end away from the bottom of the slide groove 11, and the inner end of the slide rod 7 refers to the end close to the bottom of the slide groove 11.

[0081] Exemplarily, the first elastic element 8 is one or more compression springs arranged side by side; or, as shown in Figures 4 and 5, the first elastic element 8 refers to the tail portion located at the inner end of the slide rod 7 and integrally formed with the slide rod 7, the tail portion being wavy or zigzag-shaped and capable of being elastically compressed.

[0082] The slide rod 7 is disposed on one side of the retracted position of the swing member 2. The slide rod 7 is generally L-shaped, consisting of a vertical rod and a horizontal rod. The vertical rod is located in the slide groove 11 and slides in cooperation with the slide groove 11 to guide the slide rod 7. The horizontal rod extends toward the swing member 2 and is provided withThe wedge-shaped teeth 9 face the outer end of the slide rod. The swing member 2 is provided with a groove 10 that matches the wedge-shaped teeth 9 on the side near the slide rod 7. During the swinging process of the swing member 2 swinging to the closed position, the groove 10 pushes the slide rod 7 inward through the wedge-shaped teeth 9. When the swing member 2 swings to the closed position, the wedge-shaped teeth 9 and the groove 10 are aligned. The slide rod 7 returns to the outer end under the action of the first elastic member 8. The wedge-shaped teeth 9 are engaged in the groove 10, locking the swing member 2 in the closed position.

[0083] The wedge-shaped teeth 9 have a guide slope facing the swing member 2. Optionally, the swing member 2 also has a guide slope facing the slide rod. When the wedge-shaped teeth 9 and the swing member 2 are in contact, the guide slope of the wedge-shaped teeth 9 and the guide slope on the swing member 2 cooperate to make the engagement of the wedge-shaped teeth 9 and the groove 10 smoother.

[0084] As shown in Figure 9, when the cleaning disc is installed on the cleaning equipment and driven to rotate to perform cleaning operations, if the cleaning equipment is close to an obstacle, the cleaning equipment will expand the cleaning disc to get closer to the obstacle. The expansion of the cleaning disc is existing technology and will not be described in detail in this application. Although the expanded cleaning disc can get closer to the obstacle, there are still large cleaning blind spots at the edge of the obstacle and the corner of the wall.

[0085] When the cleaning disc expands and gets close to obstacles such as walls and furniture, during the rotation of the cleaning disc, the outer end of the slide rod 7 extending out of the outer edge of the cleaning disc body 1 will be pressed by the obstacle, thereby causing the slide rod 7 to compress the first elastic member 8 and slide inward to the unlock position, thereby causing the wedge tooth 9 to disengage from the slot 10 and release the lock on the swing member 2. The swing member 2 swings to the extended position under the action of the second elastic member 3. During the swing, the outer end of the swing member 2 extends outward and always keeps in contact with the obstacle. The swing member 2 can reach the area that the cleaning disc body 1 cannot cover, thereby thoroughly cleaning the edge of the obstacle and the corner of the wall.

[0086] Referring to Figures 4 and 5, in this embodiment, preferably, the angle between the retracted position and the obstacle avoidance position, that is, the swing range of the swing member 2, is 180 degrees. The retracted position is located at 0 degrees, the extended position is located at 90 degrees, and the obstacle avoidance position is located at 180 degrees. The swing direction of the swing member 2 when it swings from the retracted position to the extended position is opposite to the rotation direction of the cleaning disc when it performs cleaning operations. The locking trigger mechanism is located on the side of the retracted position away from the extended position. That is to say, when the cleaning disc performs cleaning operations, the distribution order along the rotation direction of the cleaning disc is obstacle avoidance position, extended position, retracted position, and locking trigger mechanism. Referring to the state one of Figure 6, when approaching an obstacle, the outer end of the slide rod 7 of the locking trigger mechanism contacts the obstacle first. At this time, the outer end of the swing member 2 has not yet contacted the obstacle. Referring to state 2 in Figure 6, after the swing member 2 is unlocked, if the swing member 2 contacts the obstacle before reaching the extended position, then during the contact process with the obstacle, the obstacle exerts a reaction force on the swing member 2 in the direction of the retracted position.When the swing member 2 is impacted by an obstacle, it can swing towards the retracted position to avoid the obstacle.

[0087] Referring to state three of Figure 6, once the unlocked swing member 2 is separated from the obstacle, under the action of the second elastic member 3, the swing member 2 will swing to the extended position. Referring to state four of Figure 6, when the swing member 2 collides with the obstacle again during the rotation of the cleaning disc, the swing member 2 can swing towards the obstacle avoidance position to avoid the obstacle. The swing member 2, which is between the extended position and the obstacle avoidance position, swings back to the extended position under the action of the second elastic member 3 after being separated from the obstacle.

[0088] In this embodiment, after the swing member 2 is unlocked to the extended position, during the cleaning operation of the cleaning disc, since the obstacle avoidance direction of the swing member 2 when it collides with the obstacle is towards the obstacle avoidance position, the swing member 2 will not swing towards the retracted position during the operation, and therefore will not repeatedly engage with the locking trigger mechanism, which can reduce the wear of the swing member 2 and the locking trigger mechanism.

[0089] Example 2: Unlike Example 1, which uses wedge teeth 9 and slots 10 to lock the swing member 2 in the retracted position, this example uses a magnetic adsorption method to lock the swing member 2 in the retracted position.

[0090] A magnet is provided on the slide rod 7, and an adsorption point is provided on the side of the swing member 2 near the slide rod 7. The adsorption point can be another magnet that is attracted to the magnet on the slide rod 7, or it can be a magnetic material such as iron that can be attracted by a magnet. The other magnet or the magnetic material can be fixed to the swing member 2 by embedding, welding, gluing, screws, etc. Other positions on the swing member 2, except for the adsorption point, cannot be attracted by a magnet. When the slide bar 7 is in the locked position and the swing member 2 is in the retracted position, the magnet on the slide bar 7 is aligned with the adsorption point on the swing member 2. The magnet adsorbs the swing member 2 through the adsorption point, locking the swing member 2 in the retracted position. During the rotation of the cleaning disc, the outer end of the slide bar 7 extending out of the outer edge of the cleaning disc body 1 will be pressed by an obstacle, thereby causing the slide bar 7 to compress the first elastic member 8 and slide inward to the unlocked position. After the slide bar 7 slides to the unlocked position, the magnet on the slide bar 7 is misaligned with the adsorption point, and the magnetic attraction of the magnet to the adsorption point is drastically weakened or even disappears, which is insufficient to lock the swing member 2 in the retracted position. The swing member 2 is unlocked and swings to the extended position under the action of the second elastic member 3 and other external forces, thoroughly cleaning the edge of the obstacle and the corner of the wall.

[0091] Embodiment 3: Unlike the locking trigger mechanism of Embodiment 1 and Embodiment 2, which unlocks the swing member 2 by sliding the slide bar 7, this embodiment provides another form of locking trigger mechanism.

[0092] The locking trigger mechanism of this embodiment includes an electromagnet and a control switch. The control switch controls the energization and de-energization of the electromagnet. The electromagnet is fixed on the cleaning tray body 1 and located on one side of the retracted position of the swing member 2. The control switch is a push-button switch located on the outer edge of the cleaning tray body 1. When the control switch is not pressed, it is in a normally closed state, that is, the electromagnet is in a normally energized state.State; the swinging part 2 is made of magnetic material in whole or in part. If the swinging part 2 is partially made of magnetic material, when the swinging part 2 is in the closed position, the magnetic material is aligned with the electromagnet; the energized electromagnet can attract the swinging part 2 and lock the swinging part 2 in the closed position.

[0093] During the rotation of the cleaning disc, if the control switch on the outer edge of the cleaning disc body 1 is pressed by an obstacle, the electromagnet is de-energized, the attraction of the electromagnet to the swinging part 2 disappears, the swinging part 2 is unlocked and, under the action of the second elastic element 3, swings to the extended position to thoroughly clean the edge of the obstacle and the corner of the wall.

[0094] As the cleaning disc rotates, the control switch disengages from the obstacle, the electromagnet is energized again, and when the swinging part 2 reaches the closed position again, the swinging part 2 is attracted by the electromagnet and locked in the closed position.

[0095] In other embodiments, the control switch may be closed or opened without pressing, but rather by using a sensor control method. For example, when the distance sensor detects that the cleaning device is close to an obstacle, or when the pressure sensor detects that the outer edge of the cleaning disc body is in contact with an obstacle, the controller cuts off the power to the control switch and unlocks the swing member according to the sensor detection signal, so that the swing member swings to the extended position under the action of the second elastic member.

[0096] Example 4: Unlike the above examples, in this example, the cleaning tray body 1 does not have an installation cavity 4. Instead, a recessed groove is opened on the side of the cleaning tray body 1 facing the surface to be cleaned. The inner end of the swing member 2 is hinged to the bottom of the recessed groove through a hinge shaft. The swing member 2 is limited in the direction perpendicular to the cleaning tray body 1 by axial limiting members such as shoulders and nuts at the end of the hinge shaft to prevent the swing member 2 from falling off. The entire swing member 2 is in an exposed state. The side of the recessed groove facing the outer edge of the cleaning tray body 1 is open so that part of the swing member 2 can extend out of the recessed groove to the outside of the cleaning tray body 1. The purpose of setting the recessed groove is to make the side of the swing member 2 facing the surface to be cleaned flush with the side of the cleaning tray body 1 facing the surface to be cleaned, so that the surface of the cleaning member is flush after the cleaning member is installed.

[0097] In other embodiments, the sink may not even be required. The swing member 2 is directly hinged to the side of the cleaning tray body 1 facing the surface to be cleaned, and the swing member 2 protrudes beyond the tray surface of the cleaning tray body 1. In this case, the surfaces of the cleaning members are made flush by the thickness difference between the first cleaning member 12 on the cleaning tray body 1 and the second cleaning member 13 on the swing member 2. That is, the first cleaning member 12 is thicker and the second cleaning member 13 is thinner. After the cleaning members are installed, the total thickness of the swing member 2 and the second cleaning member 13 is equal to the thickness of the first cleaning member 12. This method has greater limitations on the selection of cleaning members.

[0098] In both of the above methods, the swing member 2 is completely exposed or even protrudes beyond the cleaning tray body 1, which affects the appearance and function of the product, but has a greater cost advantage and is suitable for basic or low-end products.

[0099] Example 5: Unlike the rod-shaped swing member 2 in the above examples, the swing member 2 in this example is disc-shaped. Preferably, the swing member 2 is a disc with a smaller diameter than the main body 1 of the cleaning disc. The swing center of the swing member 2 does not coincide with its geometric center. When the swing member 2 swings to the extended position, part of it protrudes outside the main body 1 of the cleaning disc. Although the depth of the disc-shaped swing member 2 in the corner area is not as great as that of the rod-shaped swing member 2, it can still greatly improve the cleaning coverage of the cleaning disc on the edges and corners of obstacles. More importantly, the disc-shaped swing member 2 is stronger and more stable than the rod-shaped swing member 2.

[0100] Of course, the swing member 2 can also be an elliptical disc.

[0101] Example 6: Unlike the torsion spring of the second elastic element 3 in the above examples, the second elastic element 3 in this example is a compression spring. One end of the compression spring acts on the cleaning disc body 1, for example, pressing or fixing it to the cleaning disc body 1, and the other end acts on the swinging element 2, for example, pressing or fixing it to the swinging element 2. The direction of the force exerted by the compression spring on the swinging element 2 does not pass through the swinging center of the swinging element 2, so that the force of the compression spring generates torque on the swinging element 2, so that the swinging element 2 has a tendency to swing around the swinging center towards the extension position.

[0102] The compression spring can be a conventional cylindrical compression spring, or it can be an arc-shaped compression spring with an arc-shaped axis.

[0103] Example 7: Unlike the swinging element 2 in the above examples, which swings towards the extension position by relying on the second elastic element 3, in this example, the second elastic element 3 is not provided. After the swinging element 2 is unlocked, the swinging element 2 swings towards the extension position by relying on the centrifugal force of the cleaning disc rotating. Instruction manual, pages 9 / 12, 13 CN 121549719 A

[0104] Example 8: Unlike the above examples which have a locking trigger mechanism, this example does not have a locking trigger mechanism. The swing member 2 is held in the extended position by the action of the second elastic member 3, or it is held in the extended position by centrifugal force during the rotation of the cleaning disc. When the swing member 2 collides with an obstacle, it can swing towards the retracted position to avoid the obstacle.

[0105] Example 9: In this example, the cleaning disc body 1 is provided with two or more sets of corner cleaning mechanisms. Preferably, the corner cleaning mechanisms are evenly distributed in the circumferential direction of the cleaning disc body 1.

[0106] The more corner cleaning mechanisms are provided, the larger the area occupied by the cleaning disc body 1, the smaller the area used for regular cleaning, and the more complex the structure of the cleaning disc. Therefore, the corner cleaning mechanisms are usually provided in no more than two sets.

[0107] Example 10: Based on any of the above embodiments, this embodiment can be improved as follows: Improvement 1: The outer end of the swing member 2 is provided with rounded corners to avoid scratching the wall, furniture, etc. when the outer end of the swing member 2 collides with the wall, furniture, etc., and at the same time, it can make the outer end of the swing member 2 contact the surface of the obstacle and move more smoothly along the surface of the obstacle, and can adapt to the unevenness of the obstacle surface, preventing the swing member 2 from being blocked or jammed by the obstacle.

[0108] Improvement 2: The outer end of the swing member 2 is coated with rubber to buffer when the outer end of the swing member 2 collides with the wall, furniture, etc., to avoid damage to the wall, furniture, etc. and the swing member 2, and at the same time reduce the noise during the collision.

[0109] Improvement 3: The outer end of the swing member 2 is provided with bristles, which extend away from the cleaning tray body 1. The bristles can better penetrate into the corners of the wall, the edges of obstacles, etc., for more thorough cleaning; when the outer end of the swing member 2 is coated with rubber, the bristles can be set on the rubber coating.

[0110] In this embodiment, the outer end of the swing member 2 refers to the end of the swing member 2 that extends out of the cleaning tray body 1 when the swing member 2 is in the extended position, that is, the end of the swing member 2 that collides with the obstacle.

[0111] Based on any of the above embodiments with the slide rod 7, this embodiment can be improved as follows: Improvement 4: The end of the slide rod 7 away from the first elastic member 8, that is, the end that collides with the obstacle, is provided with a rounded corner to avoid scratching the wall, furniture, etc. when the end of the slide rod 7 collides with the wall, furniture, etc.

[0112] Improvement 5: The end of the slide rod 7 away from the first elastic member 8, i.e., the end that collides with the obstacle, is coated with rubber. This is used to buffer the slide rod 7 when it collides with the wall, furniture, etc., to avoid damage to the wall, furniture, etc., and to reduce the noise during the collision.

[0113] It should be noted that the above improvements can be one or more of them.

[0114] Embodiment 11: Based on any of the above embodiments, the surface of the cleaning tray body 1 is provided with several drainage holes. The drainage holes are used to allow the cleaning water from the cleaning equipment host 14 to seep into the first cleaning member 12 and the second cleaning member 13 for cleaning.

[0115] When the cleaning tray body 1 is composed of a first tray 5 and a second tray 6, the drainage holes are composed of a first drainage hole provided on the first tray 5 and a second drainage hole provided on the second tray 6. The first drainage holes are evenly distributed around the circumference of the first tray 5, and at least some of the second drainage holes are provided on the distribution path of the first drainage holes. The first drainage holes and the second drainage holes are evenly distributed around the entire circumference, which allows the cleaning water to seep evenly onto the second cleaning component 12. Of course, more second drainage holes can also be added at other positions on the second tray 6 to supplement the water volume of the second cleaning component 13.

[0116] The following provides some embodiments of the cleaning components of the present invention.

[0117] Embodiment Twelve: Referring to Figures 7 and 8, the cleaning component of this embodiment includes a first cleaning component 12, a second cleaning component 13, and the cleaning tray in any one of the embodiments of Embodiments One to Eleven of the specification 10 / 12 pages 14 CN 121549719 A.

[0118] The first cleaning component 12 is installed on the side of the cleaning tray body 1 facing the surface to be cleaned; the second cleaning component 13 is installed on the side of the swing component 2 facing the surface to be cleaned; after installation, the first cleaning component 12 and the second cleaning component 13 are flush with each other on the side facing the surface to be cleaned.

[0119] For example, the cleaning component can be installed on the cleaning disc body 1 or the swing component 2 using Velcro, snap fasteners, or other structures; the cleaning component can be a rag, felt pad, disposable cleaning cloth, sponge, etc.

[0120] After the swing component 2 extends, the second cleaning component 13 on the swing component 2 can clean areas such as the edges of obstacles or corners.

[0121] The following provides some embodiments of the cleaning device of the present invention.

[0122] Embodiment Thirteen: The cleaning device in this embodiment includes a main unit 14 and the cleaning components in Embodiment Twelve.

[0123] The cleaning components on the cleaning device are usually provided in two. In this embodiment, one cleaning component can be the cleaning component in Embodiment Twelve, and the other can be a conventional cleaning component that does not have a corner cleaning mechanism and a locking trigger mechanism; or, both cleaning components can be the cleaning components in Embodiment Twelve.

[0124] For example, the main unit 14 usually refers to a sweeping machine, mopping machine, etc.

[0125] The cleaning component is installed on the side of the host 14 facing the surface to be cleaned through the connecting structure on the cleaning disc body 1. For example, the connecting structure adopts anti-rotation fits such as splines, flat keys, and square shafts, and is axially limited by locking screws, axial limit rings, nuts, etc. The drive motor on the host 14 drives the cleaning component to rotate forward or backward through the connecting structure. Forward rotation refers to the rotation direction of the cleaning component when performing cleaning operations, and reverse rotation is the rotation direction opposite to the forward rotation direction when not performing cleaning operations. After the cleaning component is installed on the host 14, the first cleaning component 12 and the second cleaning component 13 face the surface to be cleaned and clean the surface to be cleaned as the cleaning component rotates.

[0126] Preferably, when the cleaning component has a locking trigger device, the main unit 14 of the cleaning equipment is provided with a retracting device; in the prior art, after the cleaning equipment completes the cleaning operation, it drives the cleaning component to rotate in the opposite direction, and lifts the cleaning component away from the surface being cleaned through a threaded mechanism, thereby detaching it from the surface being cleaned; during the process of the cleaning component rotating in the opposite direction and lifting, the swinging member 2 that is not in the retracted position will contact the retracting device, and in conjunction with the rotation of the cleaning disc, the retracting device will push the swinging member 2 to the retracted position, and the swinging member 2 will be locked by the locking trigger mechanism.

[0127] Exemplarily, the retracting device is served by the outer edge of the cleaning disc body 1 of another cleaning component on the main unit 14 of the cleaning equipment. The swinging member 2 that is not in the retracted position will contact the outer edge of the other cleaning disc body 1 when it rotates in the opposite direction with the cleaning disc body 1 it is located in, and as the cleaning disc body 1 it is located in rotates, it will be pushed to the retracted position by the outer edge of the other cleaning disc body 1 and locked by the locking trigger mechanism, thus completing the retraction of the swinging member 2.

[0128] Referring to Figure 10, when neither of the two sets of cleaning components is expanded outward, there is a gap between the outer edges of the cleaning disc bodies 1 of the two sets of cleaning components to avoid interference between the two cleaning disc bodies 1. Therefore, in order for the swing member 2 to be able to be controlled by the other cleaning disc bodyWhen the outer edge is pushed to the retracted position, the swing member 2 needs to be in the retracted position. The length of the outer end of the swing member 2 extending out of the outer edge of the cleaning disc body 1 is equal to the gap between the outer edges of the two cleaning disc bodies 1. In addition, the unlocking of the locking trigger mechanism requires an obstacle to press the outer end of the slide bar 7 or the control switch. This requires that when the slide bar 7 is in the locked position, the length of the outer end of the slide bar 7 or the button of the control switch extending out of the outer edge of the cleaning disc body 1 is less than the gap between the outer edges of the two cleaning disc bodies 1, so as to avoid the locking trigger mechanism being unlocked by the outer edge of the other cleaning disc body 1.

[0129] As can be seen from the above, the length of the outer end of the swing member 2 in the retracted position extending beyond the outer edge of the cleaning disc body 1 is greater than the length of the outer end of the slide rod 7 or the button of the control switch extending beyond the outer edge of the cleaning disc body 1. It should be noted that this does not affect the outer end of the slide rod 7 or the button of the control switch being pressed by an obstacle. Referring to state one of Figure 6 and in conjunction with the description of embodiment one, when the cleaning disc performs cleaning operations and approaches an obstacle, the outer end of the slide rod 7 of the locking trigger mechanism or the button of the control switch is the first to contact the obstacle. At this time, the outer end of the swing member 2 has not yet contacted the obstacle. Therefore, the swing member 2 will not affect the outer end of the slide rod 7 or the button of the control switch being pressed by an obstacle.

[0130] In fact, in other embodiments, even when the swing member 2 is in the retracted position, the length of the extension of the outer edge of the cleaning disc body 1 is less than the length of the extension of the slide bar 7 to the outer edge of the cleaning disc body 1. The swing member 2 cannot be directly pushed to the retracted position by the outer edge of the other cleaning disc body. However, since the cleaning component rotates very fast, the force when the swing member 2 collides with the outer edge of the other cleaning disc body is sufficient to make the swing member 2 return to the retracted position by the inertia of swinging towards the retracted position after the collision.

[0131] Exemplarily, the retracting device can also be a fixed structure such as a protrusion or a fixed rod set on the main body of the cleaning device. When the cleaning component is not expanded outward, the gap between the fixed structure and the outer edge of the cleaning disc body 1 where the swing member 2 is located is equivalent to the gap between the outer edges of the two cleaning disc bodies 1. The swing member 2, which is not in the retracted position, will contact the fixed structure when it rotates in the opposite direction with the cleaning disc body 1 where it is located. As the cleaning disc body 1 rotates, it will be pushed to the retracted position by the fixed structure and then locked by the locking trigger mechanism to complete the retraction of the swing member 2.

[0132] In this embodiment, the protruding part is arranged radially along the main body of the cleaning tray, that is, it is collinear with one of the radii of the main body of the cleaning tray. The obstacle avoidance part and the retracting part are symmetrical about the protruding part. This is the simplest and most intuitive design, which not only gives the product a symmetrical aesthetic, but also makes the design of the structure of the main body of the cleaning tray and the position and swing path of the swinging part less difficult, and the processing technology of the parts is simpler. However, this also means that the swinging part is located at the obstacle avoidance part.When the swinging member extends beyond the outer edge of the cleaning disc body, it cannot completely avoid obstacles.

[0133] Of course, in other embodiments, the obstacle avoidance position and the retracted position may not be symmetrical about the extended position, or the extended position may not be arranged radially along the cleaning disc body. When the swinging member is in the obstacle avoidance position, the swinging member is completely located inside the cleaning disc body, thereby achieving complete avoidance of obstacles.

[0134] Referring to FIG10, it should be noted that although there is a gap between the outer edges of the two cleaning disc bodies 1, the radial dimension of the first cleaning member 12 installed on the cleaning disc body 1 is larger than the radial dimension of the cleaning disc body 1, so that the first cleaning members 12 of the two sets of cleaning components contact or overlap each other, and there will be no cleaning gap. Moreover, since the first cleaning member 12 is a flexible member, the interference of the two first cleaning members 12 will not cause negative effects.

[0135] The following provides some embodiments of the cleaning system of the present invention.

[0136] Example 14: The cleaning system of this example includes a base station and cleaning equipment as described in Example 13. The base station has a parking compartment for the cleaning equipment to enter. After the cleaning equipment enters the parking compartment, the base station can provide the cleaning equipment with functions such as charging, replenishment, cleaning, and maintenance.

The cleaning discincludes a cleaning disc body, at least one set of corner cleaning mechanisms is arranged on the cleaning disc body. Each corner cleaning mechanism comprises a swinging member. The swinging member has a retracted position, an extended position and an obstacle avoidance position during swinging, and can swing between the retracted position and the obstacle avoidance position. The swinging axis of the swinging member is perpendicular to the disc surface of the cleaning disc body. The extended position is disposed between the retracted position and the obstacle avoidance position. When the swinging member is located at the extended position, at least part of the swinging member extends outside the cleaning disc body. After the extended swinging member collides with an obstacle, it can swing to the obstacle avoidance position for obstacle dodging. After the swinging member extends outward, the cleaning range is effectively expanded. The swinging member can reach right indoor corners, walledges, furniture edges and other areas that cannot be covered by the cleaning disc body, so as to eliminate cleaning blind areas.
