DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] It should be noted that the terms "first," "second," and so on in the specification, claims, and drawings of this application are used to distinguish different objects, rather than to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions.

[0042] In this specification, for convenience, words and phrases indicating orientation or positional relationships, such as "middle," "upper," "lower," "front," "back," "vertical," "horizontal," "top," "bottom," "inside," and "outside," are used to illustrate the positional relationships of constituent elements with reference to the accompanying drawings. This is merely for the purpose of facilitating the description of this specification and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present disclosure. The positional relationships of constituent elements may be appropriately changed depending on the orientation of the constituent elements being described. Therefore, the present disclosure is not limited to the words and phrases described in the specification and may be appropriately replaced depending on the circumstances.

[0043] In this specification, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, indirect connections through intermediaries, or internal communication between two components. Those skilled in the art will understand the meaning of these terms in this disclosure based on the specific circumstances.

[0044] In related technologies, floor cleaning machines primarily rely on friction generated by the contact of the cleaning roller with the floor. While increasing the interference between the cleaning roller and the floor improves the cleaning effect, the user's forward or backward force needs to be increased, causing the user to feel heavy operating force, which can reduce the user's operational experience. Reducing the interference between the cleaning roller and the floor reduces the user's operating force, but also reduces the cleaning force of the cleaning roller on the opposite side, which can reduce the cleaning effect of the cleaning machine.

[0045] Please refer to Figures 1 to 6 , Figure 1 This is a schematic diagram of the bottom structure of a cleaning device provided in an embodiment of the present application. Figure 2 is a schematic cross-sectional view of a cleaning device provided in an embodiment of the present application. Figure 3 This is a structural diagram of an adjustment wheel assembly and a mounting housing provided in an embodiment of the present application. Figure 4 This is a schematic diagram of the cross-sectional structure of an adjustment wheel assembly and a mounting housing provided in an embodiment of the present application. Figure 1 , Figure 5 This is a schematic diagram of the cross-sectional structure of an adjustment wheel assembly and a mounting housing provided in an embodiment of the present application. Figure 2 , Figure 6 It is a structural schematic diagram of an adjusting wheel assembly and an elastic member provided in an embodiment of the present application.

[0046] The present application provides a cleaning device 100 to solve the technical problem in the related art that the interference between the cleaning roller 20 and the ground is large and easily reduces the user's operating experience.

[0047] The cleaning device 100 includes a housing 10, a cleaning roller 20 and an adjusting wheel assembly 30. The housing 10 encloses a receiving chamber. The cleaning roller 20 is arranged in the receiving chamber and is rotatably connected to the housing 10, and the cleaning roller 20 can rotate and clean the surface to be cleaned. The adjusting wheel assembly 30 is slidably connected to the housing 10, and the adjusting wheel assembly 30 abuts the surface to be cleaned, wherein the adjusting wheel assembly 30 can move relative to the housing 10 along a first direction D1 so that the cleaning roller 20 moves in a direction away from the surface to be cleaned, and the adjusting wheel assembly 30 can move relative to the housing 10 in the opposite direction of the first direction D1 so that the cleaning roller 20 moves in a direction close to the surface to be cleaned, and there is an angle between the first direction D1 and the surface to be cleaned.

[0048] It can be understood that the cleaning device 100 of the embodiment of the present application can be, but is not limited to, a floor cleaning tool such as a cleaning machine, a sweeping robot, and a floor scrubber.

[0049] The cleaning device 100 of this embodiment includes the shell 10 (the shell 10 includes but is not limited to the tractor frame), and the shell 10 encloses a receiving cavity, which can be used to accommodate the cleaning roller 20 and other structural parts of the cleaning device 100, and this application does not impose any restrictions on this.

[0050] The cleaning device 100 of this embodiment further includes the cleaning roller 20, which is disposed in the receiving chamber and rotatably connected to the housing 10. The cleaning roller 20 rotates to contact the surface to be cleaned (the surface to be cleaned includes but is not limited to the ground), removes stains and dust on the surface to be cleaned by physical friction, and can also bring garbage on the surface to be cleaned into the cleaning device 100 by physical friction and adhesion, and is collected by other structural components of the cleaning device 100.

[0051] It should be noted that, when the cleaning device 100 is in a normal state, in order to make the cleaning roller 20 fit more closely to the surface to be cleaned, there is a pre-pressure between the cleaning roller 20 and the surface to be cleaned. It can be understood that there is a pre-pressure between the cleaning roller 20 and the surface to be cleaned, that is, there is a certain pre-applied pressure or force between the cleaning roller 20 and the surface to be cleaned. Let this pre-pressure be N1 to ensure close contact or fit between the cleaning roller 20 and the surface to be cleaned.

[0052] It should be further explained that the housing 10 includes a front end and a rear end, and the front end and the rear end are arranged in sequence along the moving direction of the cleaning device 100, and the moving direction is the direction in which the cleaning device 100 moves during the cleaning process.

[0053] The cleaning roller 20 is arranged at the front end of the shell 10, and the rear end of the shell 10 is provided with a rear wheel 40, which is rotatably connected to the shell 10. The rear wheel 40 can be used to contact the surface to be cleaned and rotate relative to the surface to be cleaned, so that the entire cleaning device 100 can effectively move on the surface to be cleaned.

[0054] The cleaning device 100 of this embodiment further includes an adjusting wheel assembly 30, which is disposed within the housing 10 and between the cleaning roller 20 and the rear wheel 40. The adjusting wheel assembly 30 is movable relative to the housing 10 in the first direction D1 and in the direction opposite to the first direction D1. For ease of description below, the direction opposite to the first direction D1 will be referred to as the second direction D2, which should not be construed as limiting the present application.

[0055] Specifically, when the adjusting wheel 32 contacts the surface to be cleaned, if the adjusting wheel assembly 30 moves relative to the housing 10 along the first direction D1, the front end of the housing 10 will be raised, thereby raising the cleaning roller 20. An angle is formed between the first direction D1 and the surface to be cleaned, so that when the adjusting wheel assembly 30 moves along the first direction D1, the front end of the housing 10 and the cleaning roller 20 can be effectively raised. Optionally, in this embodiment, the angle α between the first direction D1 and the surface to be cleaned is in the range of 0°<α<90°. For example, in other embodiments, the angle α between the first direction D1 and the surface to be cleaned can also be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, or other values ​​between 0° and 90°, and this application is not limited thereto.

[0056] It should be noted that there are two situations in which the cleaning roller 20 is raised: one is that the cleaning roller 20 is raised to separate from the surface to be cleaned; the other is that the rotation axis of the cleaning roller 20 is raised, but the cleaning roller 20 is in contact with the surface to be cleaned. In this case, the cleaning roller 20 also exerts a pre-pressure N2 on the surface to be cleaned, and N2 is less than N1. When the adjusting wheel assembly 30 moves relative to the housing 10 along the first direction D1, the cleaning roller 20 and the surface to be cleaned can be separated or the pressure between the cleaning roller 20 and the surface to be cleaned is reduced, which can facilitate the user to operate and move the cleaning device 100, thereby reducing the operating force required by the user on the cleaning device 100 and improving the user's experience with the cleaning device 100.

[0057] Furthermore, when the adjusting wheel 32 contacts the surface to be cleaned, if the adjusting wheel assembly 30 moves relative to the housing 10 in the second direction D2, the front end of the housing 10 is depressed, thereby depressing the cleaning roller 20. It should be noted that depressing the cleaning roller 20 means lowering the rotation axis of the cleaning roller 20, and the cleaning roller 20 exerts a pre-pressure N3 on the surface to be cleaned, where N3 is greater than N1. The increased pre-pressure of the cleaning roller 20 on the surface to be cleaned can improve the cleaning effect of the cleaning roller 20 on the surface to be cleaned, thereby improving the cleaning effect of the cleaning roller 20 on the surface to be cleaned, thereby improving the cleaning effect of the cleaning device 100.

[0058] It should be noted that the cleaning device 100 includes a forward state, a backward state and a stationary state. When the cleaning device 100 is in the stationary state, the distance between the axis of the cleaning roller 20 and the surface to be cleaned is a first distance. Figure 4 As shown, when the cleaning device 100 is in the backward state, the adjusting wheel assembly 30 moves along the first direction D1 and moves to Figure 5 The position corresponding to the adjusting wheel assembly in the figure, the cleaning roller 20 moves in a direction away from the surface to be cleaned, and the distance between the axis of the cleaning roller 20 and the surface to be cleaned is a second distance. Figure 5 As shown, when the cleaning device 100 is in the forward state, the adjusting wheel assembly 30 moves in the opposite direction of the first direction D1 (the second direction D2) and moves to Figure 4, the cleaning roller 20 moves in a direction approaching the surface to be cleaned, and the distance between the axis of the cleaning roller 20 and the surface to be cleaned is a third distance, wherein the second distance is greater than the first distance, and the first distance is greater than the third distance. In other words, when the cleaning device 100 is in the forward state, the stationary state, and the backward state, respectively, the height of the axis of the cleaning roller 20 increases successively. Optionally, in other embodiments, the first distance may also be equal to the third distance, and this application is not limited thereto.

[0059] When the user pulls the cleaning device 100 to move backward, the cleaning device 100 is in a backward state, and the adjusting wheel assembly 30 can move relative to the housing 10 along the first direction D1, raising the front end of the housing 10 and the cleaning roller 20, and the cleaning roller 20 and the surface to be cleaned can be separated or the pressure between the cleaning roller 20 and the surface to be cleaned is reduced, which can reduce the pulling force required for the user to pull the cleaning device 100 and improve the user's experience with the cleaning device 100.

[0060] When the cleaning device 100 moves forward, the cleaning device 100 is in a forward state, and the adjusting wheel assembly 30 can move relative to the housing 10 along the second direction D2, pressing down the front end of the housing 10 and the cleaning roller 20. This increases the pre-pressure of the cleaning roller 20 on the surface to be cleaned, thereby improving the cleaning effect of the cleaning roller 20 on the surface to be cleaned, thereby improving the cleaning effect of the cleaning roller 20 on the surface to be cleaned, and thus improving the cleaning effect of the cleaning device 100. In addition, when the cleaning device 100 moves forward, the driving force of the cleaning device 100 is mainly the driving force of the forward rotation of the motor in the cleaning roller 20. The user does not need to push the cleaning device 100 forward, or the user only needs to provide a small thrust, which is conducive to improving the cleaning effect of the cleaning device 100 and does not affect the user's operating experience of the cleaning device 100.

[0061] In the cleaning device 100 provided in the present application, the cleaning roller 20 is arranged in the receiving cavity of the housing 10 and is rotatably connected to the housing 10, the adjusting wheel assembly 30 is slidably connected to the housing 10, the adjusting wheel assembly 30 abuts the surface to be cleaned, and the adjusting wheel assembly 30 can move relative to the housing 10 along a first direction D1 so that the cleaning roller 20 moves in a direction away from the surface to be cleaned, and the adjusting wheel assembly 30 can move relative to the housing 10 in the opposite direction of the first direction D1 so that the cleaning roller 20 moves in a direction close to the surface to be cleaned, and the first direction D1 and the surface to be cleaned have an angle. The adjusting wheel assembly 30 moves relative to the housing 10 along the first direction D1, which can lift the cleaning roller 20, separate the cleaning roller 20 and the surface to be cleaned, or reduce the pressure between the cleaning roller 20 and the surface to be cleaned, thereby reducing the pulling force required by the user to pull the cleaning device 100 and improving the user's experience of the cleaning device 100. The adjusting wheel assembly 30 moves relative to the housing 10 in the opposite direction of the first direction D1, which can press down the cleaning roller 20. The pre-pressure of the cleaning roller 20 on the surface to be cleaned is increased, which can improve the cleaning effect of the cleaning roller 20 on the surface to be cleaned, thereby improving the cleaning effect of the cleaning device 100.

[0062] Please refer again Figures 1 to 6 In one embodiment, the cleaning device 100 further includes an elastic member 50, which is respectively connected to a side of the adjusting wheel assembly 30 facing away from the cleaning roller 20 and a side of the housing 10 facing the cleaning roller 20, and the elastic member 50 has elastic potential energy. The elastic member 50 can be used to apply an elastic force F1 along the first direction D1 to the adjusting wheel assembly 30 so that the adjusting wheel assembly 30 can move along the first direction D1.

[0063] Specifically, when the cleaning device 100 is in a stationary state, the pressure of the housing 10 on the adjusting wheel assembly 30, the gravity of the adjusting wheel assembly 30, the supporting force of the surface to be cleaned on the adjusting wheel assembly 30, and the elastic force F1 of the elastic member 50 on the adjusting wheel assembly 30 are jointly applied to the adjusting wheel assembly 30, so that the adjusting wheel assembly 30 moves to a certain position of the housing 10 and maintains force balance.

[0064] like Figure 7 As shown, Figure 7 This is a schematic diagram of the cross-sectional structure of an adjusting wheel assembly and a cleaning roller provided in an embodiment of the present application. Figure 1. The dotted line plus the arrow represents the direction of the backward movement of the cleaning device, which should not be understood as a limitation of the present application. When the user pulls the cleaning device 100 to move backward, the cleaning device 100 is in a backward state, and the adjusting wheel assembly 30 is subjected to the friction force F2 of the surface to be cleaned, and the friction force F2 and the elastic force F1 are in the same direction. The newly added friction force F2 causes the adjusting wheel assembly 30 to move relative to the housing 10 along the first direction D1, thereby lifting the cleaning roller 20. Figure 7 As shown, the cleaning roller 20 is elevated along the third direction D3.

[0065] like Figure 8 As shown, Figure 8 This is a schematic diagram of the cross-sectional structure of an adjusting wheel assembly and a cleaning roller provided in an embodiment of the present application. Figure 2 . The dotted line plus the arrow represents the forward moving direction of the cleaning device, which should not be understood as limiting the present application. When the cleaning device 100 moves forward, the cleaning device 100 is in a forward state, and the friction force F3 exerted on the surface to be cleaned by the adjusting wheel assembly 30 is opposite to the direction of the elastic force F1. The newly added friction force F3 causes the adjusting wheel assembly 30 to move relative to the housing 10 along the second direction D2, thereby depressing the cleaning roller 20. Figure 8 As shown, the cleaning roller 20 is depressed along the fourth direction D4.

[0066] Optionally, in this embodiment, the elastic member 50 is a cylindrical spring. In other embodiments, the elastic member 50 may also be a torsion spring, a spring sheet, a tower spring or other elastic structural member, and this application does not impose any limitation on this.

[0067] It should be noted that during the preparation process of the cleaning roller 20, the size of the cleaning roller 20 may deviate to a certain extent. In the cleaning device in the related art, when the size of the cleaning roller deviates, it will cause different pre-pressures between different cleaning rollers and the surface to be cleaned. When the user replaces the cleaning roller, the operating push-pull force of the cleaning device for different cleaning rollers varies greatly.

[0068] In the cleaning device 100 provided in the present application, even if the size of the cleaning roller 20 deviates to a certain extent, the adjusting wheel assembly 30 can move along the first direction D1 and the second direction D2, always keeping the adjusting wheel assembly 30 in contact with the surface to be cleaned and bearing the gravity of the cleaning device 100. The pressure between the cleaning roller 20 and the surface to be cleaned can be maintained within a set range, thereby ensuring that the user's operating push-pull force of the cleaning device 100 for different cleaning rollers 20 varies little when replacing the cleaning roller 20.

[0070] Specifically, the adjusting wheel assembly 30 includes a movable bracket 31, an adjusting wheel 32 and a sliding structure 33. The adjusting wheel 32 is arranged in the movable bracket 31 and is rotatably connected to the movable bracket 31. The sliding structure 33 is arranged on the movable bracket 31, and the sliding structure 33 is arranged in the slide groove structure and can slide along the slide groove structure to drive the movable bracket 31 and the adjusting wheel 32 to move relative to the mounting shell 12.

[0071] Furthermore, the elastic member 50 is provided on a side of the movable bracket 31 away from the cleaning roller 20 , and the elastic member 50 is respectively connected to the movable bracket 31 and the mounting housing 12 .

[0072] It should be noted that, in this embodiment, the installation steps of the adjusting wheel assembly 30 are: first, the adjusting wheel 32 and the sliding structure 33 are installed in the movable bracket 31, then the movable bracket 31 is installed on the mounting shell 12, and finally, the mounting shell 12 is installed on the shell body 11, so as to realize the installation of the adjusting wheel assembly 30 on the shell 10.

[0073] Please refer to Figures 1 to 9 , Figure 9 This is a schematic diagram of the internal structure of a mounting housing provided in an embodiment of the present application. In one embodiment, the mounting housing 12 includes a first side panel and a second side panel disposed opposite each other, and the slide groove structure includes a first slide groove 131 and a second slide groove 132 disposed opposite each other. The first slide groove 131 is disposed on the first side panel, and the second slide groove 132 is disposed on the second side panel.
