[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 discloses a cleaning device 10, which can be used for cleaning floors or windows. For example, the cleaning device 10 may include a cleaning robot for cleaning floors. In some embodiments, the cleaning robot may include a sweeping robot, a mopping robot, or a combined sweeping and mopping robot, etc., and this disclosure does not limit it to this.
[0031] Please refer to Figures 1 and 2. The cleaning device 10 includes: a cleaning device body 1 and a cleaning module 3.
[0032] The cleaning module 3 is connected to the cleaning device body 1. The cleaning module 3 is used to abut against the surface to be cleaned (not shown), and the cleaning device body 1 is used to drive the cleaning module 3 to move along the first direction X, so as to clean the surface to be cleaned. In some embodiments, the surface to be cleaned can be the ground, and the first direction X is the forward direction of the cleaning device 10.
[0033] In some embodiments, the cleaning module 3 may be a sweeping module, a mop, a mop board, etc., and this disclosure does not limit it.
[0034] Referring to Figure 3, the cleaning device 10 shown in Figure 1 also includes a connecting component 2. The connecting component 2 is connected to the cleaning device body 1 and the cleaning module 3 shown in Figure 1. In some embodiments, the cleaning module 3 abuts against the surface to be cleaned. Thus, when the cleaning device 10 moves along the first direction X, the cleaning device body 1 drives the connecting component 2 to move, and the connecting component 2 drives the cleaning module 3 to move, thereby realizing the linkage between the cleaning module 3 and the cleaning device body 1.
[0035] In some implementations, the cleaning module 3 is detachably mounted on the connecting component 2 to facilitate the removal and replacement of the cleaning module 3.
[0036] In some embodiments, when the cleaning device body 1 drives the cleaning module 3 to move along the first direction X via the connecting component 2, the connecting component 2 applies a force to the cleaning module 3 toward the surface to be cleaned.
[0037] Understandably, the connecting component 2 applies a force to the cleaning module 3 in a direction closer to the surface to be cleaned, which causes the connecting component 2 to apply downward pressure to the cleaning module 3, thereby making the cleaning module 3 better contact with the surface to be cleaned, thus compensating for the degree of lifting of the cleaning module 3, and increasing the contact area between the cleaning module 3 and the surface to be cleaned, thereby improving the cleaning effect.
[0038] In some embodiments, the force applied by the connecting component 2 to the cleaning module 3 includes a force perpendicular to the direction of the surface to be cleaned and / or a force intersecting the direction of the surface to be cleaned.
[0039] In some embodiments, the surface to be cleaned is located below the cleaning module 3 (as shown in Figure 2). When the cleaning device body 1 moves the cleaning module 3 along the first direction X via the connecting component 2, the connecting component 2 is configured to apply a force perpendicular to the surface to be cleaned to the cleaning module 3, and the direction of the force is downward. This force perpendicular to the surface to be cleaned will compress the cleaning module 3 towards the surface, increasing the downward pressure on the cleaning module 3, allowing it to better contact the surface to be cleaned, thereby reducing the degree of warping of the cleaning module 3, increasing the contact area between the cleaning module 3 and the surface to be cleaned, and improving the cleaning effect. Alternatively, the connecting component 2 is configured to apply a force intersecting the surface to be cleaned to the cleaning module 3.
[0040] In some embodiments, "intersecting with the surface to be cleaned" means that the direction of the force is inclined downwards. It is understood that the inclined downward force can be decomposed into a horizontal component and a vertical component, with the vertical component pointing downwards. Thus, the vertically downward component will press the cleaning module 3 towards the surface to be cleaned, increasing the downward pressure on the cleaning module 3. This allows the cleaning module 3 to better contact the surface to be cleaned, reducing the likelihood of the cleaning module 3 lifting off its tail and increasing the contact area between the cleaning module 3 and the surface to be cleaned, thereby improving the cleaning effect. Alternatively, the connecting component 2 can simultaneously apply a force perpendicular to the surface to be cleaned and a force intersecting the surface to be cleaned to the cleaning module 3, achieving the same technical effect as the above solution, which will not be elaborated further in this disclosure.
[0041] According to the cleaning device 10 provided in the embodiments of this disclosure, when the cleaning device body 1 drives the cleaning module 3 to move along the first direction X through the connecting component 2, the connecting component 2 applies a force to the cleaning module 3 toward the surface to be cleaned, so as to compensate for the degree of the cleaning module 3 lifting off the ground, and can increase the downward pressure of the cleaning module 3 on the ground, so as to increase the contact area between the cleaning module 3 and the surface to be cleaned, thereby improving the cleaning effect.
[0042] In some embodiments, referring to FIG3, in the first direction X (forward direction), the cleaning module 3 includes a first portion 31 and a second portion 32 connected together. The first portion 31 and the second portion 32 are located on both sides of the center of gravity of the cleaning module 3 (point A in FIG3). In some embodiments, the first portion 31 is located on the side of the second portion 32 closer to the first direction X, and the second portion 32 is connected to the connecting component 2.
[0043] In this way, when the cleaning device body 1 drives the cleaning module 3 to move along the first direction X through the connecting component 2, the connecting component 2 mainly applies a force to the rear end of the cleaning module 3 in the direction of approaching the surface to be cleaned, so as to reduce the problem of the rear end of the cleaning module 3 lifting off the ground, and can increase the downward pressure of the cleaning module 3 on the ground and increase the contact area between the cleaning module 3 and the surface to be cleaned, thereby improving the cleaning effect.
[0044] In some embodiments, referring to Figure 3, the projection of the connecting component 2 onto the cleaning module 3 falls within the second portion 32.
[0045] Understandably, in the first direction X, the connecting component 2 is located at the rear end of the cleaning module 3. Thus, when the cleaning device body 1 drives the cleaning module 3 to move along the first direction X through the connecting component 2, the connecting component 2 mainly applies a force to the rear end of the cleaning module 3 in the direction of approaching the surface to be cleaned. In addition, the weight of the connecting component 2 can also provide downward pressure to the rear end of the cleaning module 3, so as to further reduce the problem of the rear end of the cleaning module 3 lifting off the ground, and further increase the downward pressure of the cleaning module 3 on the ground, as well as increase the contact area between the cleaning module 3 and the surface to be cleaned, thereby improving the cleaning effect.
[0046] In some embodiments, referring to Figure 3, the connecting component 2 includes a connecting rod 21. When the cleaning device body 1 drives the cleaning module 3 to move along the first direction X via the connecting rod 21, the connecting rod 21 applies a thrust to the cleaning module 3 so that the cleaning module 3 abuts against the surface to be cleaned.
[0047] Understandably, the direction of the thrust is towards and intersects with the surface to be cleaned. For example, if the surface to be cleaned is located below cleaning module 3 (as shown in Figure 2), the direction of the thrust is inclined downwards. In this case, the thrust can be decomposed into a horizontal component and a vertical component, with the vertical component pointing downwards. Thus, the downward vertical component will compress cleaning module 3 towards the surface to be cleaned.
[0048] It should be noted that in related technologies, the cleaning device body applies a pulling force to the cleaning module 3 via the connecting component 2, with the pulling force directed upwards at an angle. This pulling force can be decomposed into a horizontal component and a vertical component, with the vertical component pointing upwards. Consequently, the upward vertical component causes the cleaning module 3 to tend to move away from the surface to be cleaned, leading to the problem of the cleaning module 3 exhibiting a "tail-like" lifting effect.
[0049] In some embodiments, the connecting rod 21 applies a thrust to the cleaning module 3, and the vertical downward component of the thrust will squeeze the cleaning module 3 toward the surface to be cleaned, thereby increasing the downward pressure of the cleaning module 3, so that the cleaning module 3 can better contact the surface to be cleaned, thereby compensating for the degree of the cleaning module 3 lifting off the top, and increasing the contact area between the cleaning module 3 and the surface to be cleaned, thereby improving the cleaning effect.
[0050] In some embodiments, referring to Figure 3, the extension line of the extension direction of the link 21 intersects the first direction X. Therefore, the extension direction of the link 21 is set to be the same as the direction of the thrust, so as to better apply thrust to the cleaning module 3.
[0051] In some embodiments, the intersection of the extension line of the link 21 and the cleaning module 3 in the extending direction of the link 21 is located on the side of the center of gravity of the cleaning module 3 (e.g., point A in FIG. 3) closer to the first direction X. This enhances the pushing force of the link 21 on the first portion 31 of the cleaning module 3 closer to the first direction X, reduces the degree of tailing on the side of the cleaning module 3 away from the first direction X, and thus improves the cleaning effect.
[0052] In some embodiments, the intersection of the extension line of the link 21 and the cleaning module 3 in the extending direction of the link 21 is located on the side of the center of gravity of the cleaning module 3 (e.g., point A in FIG. 3) away from the first direction X. This enhances the pushing effect of the link 21 on the side of the cleaning module 3 away from the first direction X, reducing the risk of tailing on that side and thus improving the cleaning effect.
[0053] In some embodiments, the intersection of the extension line of the link 21 and the cleaning module 3 in the extension direction of the link 21 is the center of gravity of the cleaning module 3 (e.g., point A in Figure 3). This enhances the pushing effect of the link 21 on the cleaning module 3 and makes the force on both sides of the center of gravity of the cleaning module 3 (point A in Figure 3) more balanced.
[0054] In some embodiments, the connecting component 2 further includes a lifting member (not shown). The lifting member connects the cleaning device body 1 and the cleaning module 3, and is used to drive the cleaning module 3 to rise or fall along a second direction Y; the second direction Y is perpendicular to the first direction X. Thus, the lifting member can be used to raise or lower the cleaning module 3.
[0055] For example, the second direction Y is the up-down direction in Figure 2, and the lifting component can drive the cleaning module 3 to rise or fall along the second direction Y. After the cleaning module 3 rises, it can be stored in the cleaning equipment body 1 to reduce the overall volume of the cleaning equipment 10. After the cleaning module 3 falls, it can extend out of the cleaning equipment body 1 to clean the surface to be cleaned.
[0056] Therefore, the cleaning module 3 can be raised or lowered by the lifting component, thereby switching the mode of the cleaning module 3.
[0057] 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.
[0058] In some embodiments, one end of the connecting rod 21 is hinged to the cleaning device body 1, and the other end of the connecting rod 21 is hinged to the cleaning module 3.
[0059] Therefore, when the lifting component drives the cleaning module 3 to rise or fall along the second direction Y, the connecting rod 21 and the cleaning equipment body 1 can rotate relative to each other, and the cleaning module 3 and the connecting rod 21 can also rotate relative to each other. This allows the connecting rod 21 to rotate to match the switching of the lifting state of the cleaning module 3, so as to better realize the rising or falling of the cleaning module 3.
[0060] In some implementations, referring to Figure 3, the connecting assembly 2 further includes a connecting seat 22. The connecting seat 22 is used to connect to the cleaning device body 1. One end of the connecting rod 21 is hinged to the connecting seat 22, and the other end of the connecting rod 21 is hinged to the cleaning module 3.
[0061] Therefore, the connecting seat 22 provides a mounting position for the connecting rod 21, and when the lifting component drives the cleaning module 3 to rise or fall in the second direction Y, the connecting rod 21 and the connecting seat 22 can rotate relative to each other, and the cleaning module 3 and the connecting rod 21 can also rotate relative to each other. In this way, the connecting rod 21 can rotate to match the switching of the state of the cleaning module 3, so as to better realize the rising or falling of the cleaning module 3.
[0062] In some implementations, the lifting component is mounted on the connecting seat 22 so that the connecting seat 22 can be used to set up an installation position for the lifting component, thereby reducing the installation difficulty of the lifting component.
[0063] In some embodiments, please refer to FIG3, there are multiple links 21, and the multiple links 21 are spaced apart in the second direction Y.
[0064] Therefore, by setting multiple connecting rods 21, the connection stability between the cleaning equipment body 1 and the cleaning module 3 can be enhanced, and the thrust of the connecting rods 21 on the cleaning module 3 can be enhanced through multiple connecting rods 21, thereby compensating for the degree of tail lifting of the cleaning module 3, increasing the downward pressure of the cleaning module 3 on the ground, and increasing the contact area between the cleaning module 3 and the surface to be cleaned, thereby improving the cleaning effect.
[0065] In some embodiments, referring to Figure 3, any two links 21 are arranged parallel or approximately parallel. In some embodiments, approximately parallel means having an included angle of 4 to 6 degrees. This ensures that any two links 21 will not interfere with each other, reducing the difficulty of arranging multiple links 21.
[0066] In some embodiments, there are at least two connecting components 2. Referring to Figure 4, at least two connecting components 2 are evenly distributed on both sides of the center of gravity of the cleaning module 3 (point A in Figure 3).
[0067] Therefore, by setting multiple connecting components 2, forces are applied to the cleaning module 3 at multiple positions on the cleaning module 3 in a direction close to the surface to be cleaned, thereby increasing the downward pressure of the cleaning module 3 on the ground, reducing the degree of lifting of the cleaning module 3, and thus increasing the contact area between the cleaning module 3 and the surface to be cleaned, thereby improving the cleaning effect.
[0068] 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.
[0069] The above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit it.
