Technical Field

[0001] This disclosure relates to the field of cleaning apparatus technology, and more particularly to a cleaning device. Background Technology

[0002] In related technologies, when the cleaning equipment moves forward, the cleaning module is pulled by a tension force, causing the rear end of the cleaning module to tilt forward. This reduces the downward pressure between the cleaning module and the ground, and also reduces the contact area, resulting in a poorer cleaning effect. Utility Model Content

[0028] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0029] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0030] This disclosure proposes a cleaning device 10, which can be used for cleaning floors or windows. For example, the cleaning device 10 can be a sweeping robot, a mopping robot, or a sweeping and mopping robot, etc. This disclosure does not limit it.

[0031] Please refer to Figure 1 and Figure 2 The cleaning equipment 10 includes a cleaning equipment body 1 and a cleaning module 3.

[0032] The cleaning module 3 is connected to the cleaning device body 1 and is used to abut against the surface 20 to be cleaned. The cleaning device body 1 is used to drive the cleaning module 3 to move along the first direction X to clean the surface 20 to be cleaned. The surface 20 to be cleaned can be the ground, and the first direction X is the forward direction of the cleaning device 10.

[0033] The cleaning module 3 can be a sweeping module, a mop, a mop board, etc., and this disclosure does not limit it.

[0034] In some implementations, the cleaning module 3 is detachably installed on the cleaning equipment body 1 so as to enable the removal and replacement of the cleaning module 3.

[0035] Cleaning module 3 has extended and retracted states, such as... Figure 1 As shown, when the cleaning module 3 is in the extended state, it extends out of the cleaning device body 1 to abut against the surface 20 to be cleaned. Figure 2 As shown, when the cleaning module 3 is in the retracted state, it is housed within the cleaning device body 1 to prevent friction between the cleaning module 3 and the surface to be cleaned. When the cleaning module 3 is in the extended state, it is also in motion (e.g., vibrating or being pulled).

[0036] Typically, when the surface to be cleaned 20 is horizontal and located below the cleaning module 3 (e.g., ...), Figure 1When the cleaning module 3 is positioned below the surface to be cleaned (as shown in the image), the pulling force applied by the cleaning device body 1 to the cleaning module 3 should be sufficient to keep the cleaning module 3 parallel to the surface to be cleaned 20, allowing the cleaning module 3 to clean the surface 20 more effectively. However, when the cleaning device body 1 moves the cleaning module 3 along the first direction X, the pulling force applied by the cleaning device body 1 to the cleaning module 3 is usually inclined upwards. This pulling force can be decomposed into a horizontal component and a vertical component, with the vertical component pointing upwards. Consequently, under the action of the vertical component, the cleaning module 3 will tilt forward, meaning the rear end of the cleaning module 3 will lift up, thus affecting the cleaning effect.

[0037] To compensate for the raised rear end of the cleaning module 3, this embodiment of the present disclosure sets a preset angle between the cleaning module 3 and the surface 20 to be cleaned when the cleaning module 3 is in the extended state. This preset angle ensures that when the cleaning module 3 is not in contact with the surface 20, the end of the cleaning module 3 facing the first direction X is raised, and the end of the cleaning module 3 away from the first direction X is lowered. This preset angle is the angle between the cleaning module 3 and the surface 20 to be cleaned under these conditions.

[0038] When the cleaning device body 1 applies a pulling force to the cleaning module 3 to pull the cleaning module 3, the cleaning module 3 can be made parallel to the surface 20 to be cleaned. Specifically, the vertical component of the pulling force causes the rear end of the cleaning module 3 (the end of the cleaning module 3 facing away from the first direction X) to rotate at a preset angle to achieve parallelism between the cleaning module 3 and the surface 20 to be cleaned. This compensates for the forward tilting (rear end lifting) of the cleaning module 3 caused by the aforementioned vertical component force under normal circumstances. At the same time, it increases the downward pressure and contact area between the cleaning module 3 and the ground, thereby improving the cleaning effect of the cleaning device 10.

[0039] According to the cleaning device 10 provided in this embodiment, the cleaning module 3 has a preset angle with the surface 20 to be cleaned when it is extended. In this way, when the cleaning device body 1 applies a pulling force to the cleaning module 3 to make the cleaning module 3 move along the surface 20 to be cleaned, the preset angle between the cleaning module 3 and the surface 20 to be cleaned will compensate for the forward tilt angle of the rear end of the cleaning module 3 caused by the pulling force applied by the cleaning device body 1 to the cleaning module 3, thereby making the cleaning module 3 parallel to the surface 20 to be cleaned, thereby increasing the downward pressure and contact area between the cleaning module 3 and the ground, and improving the cleaning effect of the cleaning device 10.

[0040] In some embodiments, please refer to Figure 3 The cleaning device 10 also includes: a connecting component 2, which connects to the cleaning device body 1 (e.g., ...). Figure 1 The cleaning device 10 consists of a main body 1 and a cleaning module 3. When the cleaning device 10 moves along the first direction X, the main body 1 drives the connecting component 2, and the connecting component 2 drives the cleaning module 3, thus realizing the linkage between the cleaning module 3 and the main body 1.

[0041] The connecting component 2 is configured to control the cleaning module 3 to switch between an extended state and a moving state. It can be understood that when the cleaning module 3 is in the extended state, the cleaning module 3 is in a stationary state. At this time, the connecting component 2 is connected between the cleaning device body 1 and the cleaning module 3 to apply a force to the cleaning module 3 so that the cleaning module 3 and the surface 20 to be cleaned have a preset angle.

[0042] When the cleaning module 3 is in motion, the cleaning device body 1 pulls the cleaning module 3 through the connecting component 2. At this time, the connecting component 2 applies a pulling force to the cleaning module 3 so that the cleaning module 3 is parallel to the surface to be cleaned 20, thereby compensating for the forward tilt of the cleaning module 3 caused by the pulling force applied by the cleaning device body 1 to the cleaning module 3 under normal circumstances.

[0043] Therefore, the extension state and movement state of the cleaning module 3 are both realized by the connecting component 2, and the switching between the extension state and movement state of the cleaning module 3 is also realized by the connecting component 2, thereby reducing the difficulty of switching.

[0044] In some embodiments, please refer to Figure 3 The connecting component 2 includes a connecting rod 21, the extension direction of which intersects with the surface to be cleaned 20 so that the cleaning module 3 and the surface to be cleaned 20 have a preset angle.

[0045] Therefore, when the cleaning module 3 is in the extended state, the connecting rod 21 can push against the cleaning module 3 so that the cleaning module 3 and the surface to be cleaned 20 have a preset angle, thereby reducing the design difficulty of the extended state, and the structure of the connecting rod 21 is relatively simple, which helps to reduce costs.

[0046] In some embodiments, please refer to Figure 4 Link 21 (e.g.) Figure 3 There are two connecting rods 21, namely the first connecting rod 211 and the second connecting rod 212, and the extension direction of the first connecting rod 211 intersects the extension direction of the second connecting rod 212.

[0047] It is understandable that the extension directions of the first link 211 and the second link 212 are different, resulting in a non-parallel design of the first link 211 and the second link 212. This makes the directions of the force exerted by the first link 211 on the cleaning module 3 and the force exerted by the second link 212 on the cleaning module 3 different, so that the cleaning module 3 and the surface to be cleaned 20 have a preset angle.

[0048] In some embodiments, please refer to Figure 4 Cleaning equipment body 1 (e.g.) Figure 1The cleaning device body 1) is provided with a first connecting seat 11 perpendicular to the surface to be cleaned 20, and the cleaning module 3 is provided with a second connecting seat 31 perpendicular to the cleaning module 3. The first connecting rod 211 and the second connecting rod 212 are both connected between the first connecting seat 11 and the second connecting seat 31.

[0049] Therefore, by setting the first connecting seat 11 and the second connecting seat 31, the design difficulty of connecting the first connecting rod 211 and the second connecting rod 212 between the cleaning equipment body 1 and the cleaning module 3 is reduced.

[0050] In some embodiments, the line connecting the first link 211 to the first connecting seat 11 and the second link 212 to the first connecting seat 11 is perpendicular to the surface 20 to be cleaned. Please refer to... Figure 4 The distance from the connection point of the first link 211 and the first connecting seat 11 to the connection point of the second link 212 and the first connecting seat 11 is L1, and the distance from the connection point of the first link 211 and the second connecting seat 31 to the connection point of the second link 212 and the second connecting seat 31 is L2, and L1 is less than L2.

[0051] It is understandable that if L1 and L2 are the same, it means that the first link 211 and the second link 212 are parallel. In that case, the force of the first link 211 on the cleaning module 3 and the force of the second link 212 on the cleaning module 3 are in the same direction, and it is impossible to achieve a preset angle between the cleaning module 3 and the surface to be cleaned 20.

[0052] Therefore, in this disclosure, L1 is less than L2, which makes the directions of the force of the first link 211 on the cleaning module 3 and the force of the second link 212 on the cleaning module 3 different, so that the cleaning module 3 and the surface to be cleaned 20 have a preset angle. At the same time, since L1 is less than L2, the preset angle between the cleaning module 3 and the surface to be cleaned 20 is located in a different direction from the forward tilt angle of the rear end of the cleaning module 3 caused by the tension applied by the cleaning device body 1 to the cleaning module 3. Thus, when the cleaning device body 1 applies a tension to the cleaning module 3 to make the cleaning module 3 move along the surface to be cleaned 20, the preset angle between the cleaning module 3 and the surface to be cleaned 20 will compensate for the forward tilt angle of the rear end of the cleaning module 3 caused by the tension applied by the cleaning device body 1 to the cleaning module 3, thereby making the cleaning module 3 parallel to the surface to be cleaned 20.

[0053] In some embodiments, in the extended state, the angle between the line connecting the first link 211 and the second connecting seat 31 to the line connecting the second link 212 and the second connecting seat 31 and the perpendicular line of the surface to be cleaned 20 is a preset angle.

[0054] For example, please refer to Figure 5In the extended state, the surface to be cleaned 20 can be a horizontal plane, and the vertical line of the surface to be cleaned 20 is B. The connection point between the first connecting rod 211 and the first connecting seat 11 can be represented by point E, the connection point between the first connecting rod 211 and the second connecting seat 31 can be represented by point G, the connection point between the second connecting rod 212 and the first connecting seat 11 can be represented by point N, and the connection point between the second connecting rod 212 and the second connecting seat 31 can be represented by point M.

[0055] At this time, EG = NM, and the angle between GM and the vertical line B is α, which is equivalent to the second connecting seat 31 rotating clockwise by α. Since the second connecting seat 31 is perpendicular to the cleaning module 3, it is equivalent to the cleaning module 3 rotating clockwise by α, that is, the preset angle between the cleaning module 3 and the surface 20 to be cleaned is α.

[0056] When the cleaning device 10 moves along the first direction X, the direction of the force exerted by the first link 211 and the second link 212 will cause the cleaning module 3 to rotate counterclockwise by the same degree as the preset angle, thereby making the cleaning module 3 parallel to the surface 20 to be cleaned.

[0057] In some embodiments, the cleaning module 3 also includes a retracted state, in which the cleaning module 3 is retracted into the cleaning device body 1 and is parallel to or has the preset angle with the surface to be cleaned 20. Please refer to... Figure 2 When the cleaning module 3 is in the storage state, the cleaning module 3 is stored in the main body 1 of the cleaning device to reduce the overall volume of the cleaning device 10 and reduce the difficulty of storage.

[0058] At the same time, it can reduce the impact on the overall appearance of the cleaning equipment 10. For example, please refer to... Figure 6 When the cleaning module 3 is in the storage state, the surface to be cleaned 20 can be a horizontal plane, the vertical line of the surface to be cleaned 20 is B, the connection point between the first connecting rod 211 and the first connecting seat 11 can be represented by point E, the connection point between the first connecting rod 211 and the second connecting seat 31 can be represented by point F, the connection point between the second connecting rod 212 and the first connecting seat 11 can be represented by point N, and the connection point between the second connecting rod 212 and the second connecting seat 31 can be represented by point H.

[0059] The first connecting rod 211 and the second connecting rod 212 are both hinged to the first connecting seat 11, and the first connecting rod 211 and the second connecting rod 212 are both hinged to the second connecting seat 31. When the cleaning module 3 switches from the extended state to the retracted state, the first connecting rod 211 and the second connecting rod 212 rotate relative to the first connecting seat 11 and the second connecting seat 31 so that the cleaning module 1 is retracted into the cleaning equipment body 1.

[0060] When the cleaning module 3 is in its retracted state, it is typically parallel to the surface 20 to be cleaned. In this case, the connection points of the first connecting rod 211 and the second connecting seat 31, and the second connecting rod 212 and the second connecting seat 31, need to be on the same vertical line. This ensures that the first connecting rod 211 and the second connecting rod 212 exert a pulling force on the second connecting seat 31 in the same vertical direction, guaranteeing the parallelism between the cleaning module 3 and the surface 20 to be cleaned. However, in this disclosure, the distance from the connection point of the first connecting rod 211 and the first connecting seat 11 to the connection point of the second connecting rod 212 and the first connecting seat 11 is less than the distance between the first connecting rod 211 and the second connecting seat 31. The distance from the connection point of 31 to the connection point of the second connecting rod 212 and the second connecting seat 31 is such that, in order to achieve the parallel arrangement of the first connecting rod 211 and the second connecting rod 212, points N and E need to be set not to be on the same vertical line. Specifically, point N is located on the side of the perpendicular line passing through point E closer to the first direction X. In this way, when the cleaning module 3 is housed in the cleaning device body 1, EF = NH, and FH is parallel to the perpendicular line B. Therefore, the cleaning module 3 is parallel to the surface to be cleaned 20, thus keeping the gap between the cleaning module 3 and the cleaning device body 1 horizontal, thereby reducing the impact on the overall appearance of the cleaning device 10. However, it is understandable that when the cleaning module 3 is in the housed state, the cleaning module 3 can also have the aforementioned preset angle with the surface to be cleaned 20, thereby reducing the design difficulty.

[0061] In some embodiments, a lifting member (not shown) is also included, which is connected between the cleaning device body 1 and the cleaning module 3, and is configured to drive the cleaning module 3 to switch between an extended state and a retracted state. Thus, the lifting member can be used to switch the cleaning module 3 between an extended state and a retracted state.

[0062] In some implementations, the lifting component includes an electric telescopic rod, a pull rope, or other structures capable of lifting, which are not limited in this disclosure.

[0063] In some embodiments, the two ends of the connecting component 2 are hinged to the cleaning device body 1 and the cleaning module 3, respectively.

[0064] Therefore, when the lifting component drives the cleaning module 3 to switch between the extended state and the retracted state, the connecting component 2 and the cleaning device body 1 can rotate relative to each other, and the cleaning module 3 and the connecting component 2 can also rotate relative to each other. This allows the connecting component 2 to match the state switching of the cleaning module 3, so as to better realize the switching of the cleaning module 3 between the extended state and the retracted state.

[0065] In some embodiments, the preset included angle is greater than or equal to 4° and less than or equal to 6°.

[0066] For example, the preset included angle can be 4°, 5°, or 6°. That is, when the preset included angle is within the above range, it can ensure that the cleaning module 3 and the surface to be cleaned 20 have a preset included angle, while avoiding the preset included angle being too large, thereby reducing the difficulty of compensating for the forward tilt angle of the cleaning module 3 when the cleaning device body 1 applies a pulling force to the cleaning module 3.

[0067] It should be noted that the descriptions of each embodiment in the above embodiments have different focuses. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0068] The above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit it.
