Description

Technical Field

[0001] The invention relates to the technical field of cleaning appliances, and in particular to a cleaning appliance. Background Art

[0002] With the development of science and technology and the improvement of people's living standards, there are many types of window cleaning machines on the market. However, the window cleaning machines in the prior art have defects, such as:

[0003] When cleaning a surface to be cleaned, a window cleaning machine in the prior art usually moves and cleans the surface to be cleaned by using a dual-wheel motion mode of one stationary and one dynamic, that is, one travel turntable is adsorbed on the surface to be cleaned, and the other travel turntable rotates and moves, so as to clean the surface to be cleaned by twisting and driving. In this cleaning mode, since one travel turntable is always in a stationary state, the cleaning efficiency of the window cleaning machine is low, the window cleaning time is long, it is easy to waste electric energy, and it is easy to fall off the surface to be cleaned.

[0004] When the window cleaning machine in the prior art moves on the surface to be cleaned, the pressure applied by the travel turntable to the surface to be cleaned is equal everywhere, and the friction between the surface to be cleaned and each point of the travel turntable is also equal everywhere, which makes it easy for the surface to be cleaned and the travel turntable to generate a reverse torsional force that resists the rotation of the travel turntable, making it difficult for the travel turntable to move stably and quickly on the surface to be cleaned.

[0005] The adsorption and movement functions of the window cleaning machine in the prior art are integrated on the travel turntable, and the travel turntable must be firmly adsorbed on the surface to be cleaned while rotating. This arrangement makes it easy for the travel turntable to have poor adsorption with the surface to be cleaned when rotating, causing the travel turntable to fall off the surface to be cleaned, and the cleaning surface of the travel turntable can only fit tightly with the surface to be cleaned. When there is an inclination angle between the cleaning surface of the travel turntable and the surface to be cleaned, the travel turntable will directly fall off the surface to be cleaned, which limits the use range of the travel turntable and makes it difficult to adapt to complex cleaning environments.

Among them, the adsorption device 3 can be fixed relative to the main body 1, and can also be rotated counterclockwise or clockwise through the first transmission structure 20 or the walking device inside the main body 1; the external surface to be cleaned 35 includes the surface of the door and / or window, preferably the surface of the glass window. The cleaning piece can be selected as a rag, a disposable rag, etc. The moving device 2 is a walking device with a moving function.

[0076] Specifically, the present embodiment can realize the movement of the mobile device 2, such as the function that each group of walking turntables 5 mentioned below moves and the whole cleaner moves in a straight line, which can make the walking turntable 5 move more stably on the external surface to be cleaned 35, so that the cleaner can adapt to a variety of complex cleaning environments, and greatly improve the moving speed of the cleaner, which is beneficial to improving the cleaning efficiency of the cleaner, and reduces the power consumption of the cleaner when wiping the surface to be cleaned 35 per unit area, thereby saving energy and improving the user experience.

[0077] In this embodiment, the moving device 2 includes at least two travel turntables 5, and the at least two travel turntables 5 are used to drive the main body 1 to move by rotating; each travel turntable 5 can be rotatably arranged on the main body 1, and the adsorption device 3 includes at least one adsorption disk 4, each adsorption disk 4 is provided with an adsorption space, and each adsorption space is provided with at least one travel turntable 5, or is empty.

[0083] In this embodiment, the adsorption disk 4 rotates relative to the main body 1. It can be understood that the adsorption disk 4 can be connected to the travel turntable 5, and the adsorption disk 4 is driven to rotate during the rotation of the travel turntable 5.

[0117] The other features of this embodiment are the same as those of Embodiment 1 and will not be described in detail.

[0118] Example 4

[0119] like Figure 14-17 As shown, this embodiment provides a cleaner. Compared with embodiment 1, the main difference of this embodiment is:

[0120] In this embodiment, the adsorption device 3 includes an adsorption disk 4, and an adsorption space is formed in the adsorption disk 4; the moving device 2 includes two walking turntables 5, and at least one of the two walking turntables 5 is located in the adsorption disk 4. Specifically, the two walking turntables 5 are respectively a first walking turntable 8 and a second walking turntable 9, and at least one of the first walking turntable 8 and the second walking turntable 9 is located in the adsorption disk 4; or, both walking turntables 5 are located outside the adsorption space.

[0121] Specifically, a single adsorption plate 4 is installed on the main body 1, which has no limited outline shape and no limited whether to include the first travel turntable 8 and the second travel turntable 9. The adsorption plate 4 can move up and down along the vertical direction of the main body 1 (i.e., the vertical direction of the glass surface), and can be rotated. Optionally, the adsorption plate 4 in this embodiment can be a ring-shaped adsorption plate 4 set at the bottom edge of the main body 1, and can optionally include both the first travel turntable 8 and the second travel turntable 9.

[0122] Specifically, in the present embodiment, the two walking turntables 5 may also be located outside the adsorption space. Specifically, in order to further enhance the walking ability (moving ability) of the cleaner, the present embodiment may add walking turntables 5 in pairs, and in order to better increase the adsorption capacity, no less than one adsorption plate 4 may be provided; that is, the moving device 2 may optionally include four walking turntables 5, and each walking turntable 5 may be rotatably provided on the main body 1; the adsorption plate 4 may optionally include one adsorption plate 4, and the four walking turntables 5 may optionally be located outside a single adsorption plate 4, and a single adsorption plate 4 may be provided between the four walking turntables 5; the shape of the adsorption plate 44 may include a rectangle, annular, triangle, circle or diamond, etc. Figure 14-15 In the figure, the two travel turntables 5 (the first travel turntable 8 and the second travel turntable 9) are both located in the adsorption space of the adsorption disk 4.

[0123] In Example 1, the adsorption device 3 includes two adsorption disks 4, each of which is provided with an adsorption space; the moving device 2 includes two travel turntables 5, and the two travel turntables 5 are respectively located in two adsorption spaces.

[0124] Therefore, it is different from the present embodiment.

[0125] The other features of this embodiment are the same as those of Embodiment 1 and will not be described in detail.

[0126] Example 5

[0127] like Figure 18-Figure 20 As shown, this embodiment provides a cleaner. Compared with embodiment 1, the main difference of this embodiment is:

[0128] In this embodiment, the adsorption device 3 includes two adsorption plates 4 ; the moving device 2 includes two travel turntables 5 , and the two adsorption plates 4 are respectively located in the two travel turntables 5 .

[0129] Specifically, the adsorption device 3 may optionally include two adsorption plates 4, which are a first adsorption plate 6 and a second adsorption plate 7; the moving device 2 may optionally include two walking turntables 5, which are a first walking turntable 8 and a second walking turntable 9, respectively. The first adsorption plate 6 is located in the first walking turntable 8, and the second adsorption plate 7 is located in the second walking turntable 9. The adsorption device 3 in this embodiment does not move relative to the main body 1.

[0130] In this embodiment, a connecting shaft is also included, which connects the main body 1 and the adsorption disk 4; the connecting surface of the connecting shaft connected to the adsorption disk 4 is perpendicular to the central axis of the main body 1, specifically, vertical means completely vertical or substantially vertical.

[0131] Specifically, the extension direction of the connecting shaft is inclined relative to the central axis of the main body 1, and the connecting surface at the end of the connecting shaft is basically flat, so that the angle between the adsorption disk 4 and the surface to be cleaned 35 can basically reach 0 degrees. Optionally, the transmission assembly is sleeved outside the connecting shaft and is spaced from the connecting shaft. That is, the connecting shaft and the transmission assembly do not affect each other. The transmission assembly is connected to the walking turntable, and the central axis of the transmission assembly is inclined relative to the central axis of the main body so that the walking turntable is inclined. The extension direction of the connecting shaft can be inclined relative to the central axis of the main body so that the connecting shaft can be set without interfering with the transmission assembly. The connecting surface of the connecting shaft connected to the adsorption disk 4 is perpendicular to the central axis of the main body 1, which makes the connecting surface at the end of the connecting shaft basically flat, so that the angle between the adsorption disk 4 and the surface to be cleaned 35 can basically reach 0 degrees. That is, during the operation of the cleaner, the adsorption disk 4 can be better adsorbed on the surface to be cleaned.

[0132] It can be understood that the two connecting shafts are respectively the third fixing member 32 and the fourth fixing member 33 described below. The first end of the third fixing member 32 is connected to the first adsorption disk 6, and the second end of the third fixing member 32 is fixedly connected to the main body 1, and is not connected to the first transmission mechanism, so that the first adsorption disk 6 cannot rotate; the first end of the fourth fixing member 33 is connected to the second adsorption disk 7, and the second end of the fourth fixing member 33 is fixedly connected to the main body 1, and is not connected to the first transmission mechanism, so that the second adsorption disk 7 cannot rotate.

[0133] In Example 1, the adsorption device 3 includes two adsorption disks 4, each of which is provided with an adsorption space; the moving device 2 includes two travel turntables 5, and the two travel turntables 5 are respectively located in two adsorption spaces.

[0134] Therefore, it is different from the present embodiment.

[0135] The other features of this embodiment are the same as those of embodiment 1 and will not be described in detail.

[0136] This embodiment provides a cleaner. Compared with Embodiment 5, the main differences of this embodiment are:

[0137] In this embodiment, the first end of the third fixing member 32 is connected to the first adsorption plate 6 and the adsorption plate 4, and the first walking turntable 5 is connected to the second end of the third fixing member 32, and is used to drive the first adsorption plate 6 and the adsorption plate 4 to rotate, so that the first adsorption plate 6 and the adsorption plate 4 can rotate relative to the main body 1; the first end of the fourth fixing member 33 is connected to the second adsorption plate 4, and the second walking turntable 5 is connected to the second end of the fourth fixing member 33, and is used to drive the second adsorption plate 4 to rotate, so that the second adsorption plate 4 can rotate relative to the main body 1.

[0138] In Example 5, the first end of the third fixing member 32 is connected to the first adsorption plate 6 and the adsorption plate 4, and the second end of the third fixing member 32 is fixedly connected to the main body 1, and is not connected to the first transmission mechanism, so that the first adsorption plate 6 and the adsorption plate 4 cannot rotate; the first end of the fourth fixing member 33 is connected to the second adsorption plate 4, and the second end of the fourth fixing member 33 is fixedly connected to the main body 1, and is not connected to the first transmission mechanism, so that the second adsorption plate 4 cannot rotate.

[0139] Therefore, it is different from the present embodiment.
