DETAILED DESCRIPTION

[0025] Hereinafter, various embodiments disclosed in the present application will be described more fully. The present application may have various embodiments, and adjustments and changes may be made therein. However, it should be understood that there is no intention to limit the various embodiments disclosed in the present application to the specific embodiments disclosed herein, but the present application should be understood to cover all adjustments, equivalents and / or alternatives falling within the spirit and scope of the various embodiments disclosed in the present application.

[0026] The present application discloses a cleaning machine, which can perform multiple cleaning operations with the aid of two cleaning parts with different cleaning effects, thereby improving the cleaning effect on stubborn stains and reducing the number of times the cleaning cloth is replaced. Figure 1 The specific plan is as follows:

[0027] A cleaning machine comprises a main body 1 and at least two cleaning units 2 located on the same side of the main body 1. The main body 1 is provided with a negative pressure device 5 connected to the cleaning unit 2. The negative pressure device 5 is used to extract air in the cleaning unit 2 so that the cleaning machine is adsorbed onto the surface to be cleaned. The cleaning unit 2 comprises a first type of cleaning member 44 and a second type of cleaning member 43. The first type of cleaning member 44 is located outside the second type of cleaning member 43 so that the first type of cleaning member 44 cleans the surface to be cleaned before the second type of cleaning member 43. Figure 1 The positions of the first type cleaning member 44 and the second type cleaning member 43 are schematically shown. The first type cleaning member 44 and the second type cleaning member 43 have different cleaning effects, and the cleaning effect can be changed by setting parameters such as the cleaning method, material, rotation speed, and force of the first type cleaning member 44 and the second type cleaning member 43.

[0028] In some specific embodiments, the first type of cleaning member 44 cleans the surface to be cleaned in a different manner than the second type of cleaning member 43, so that the first type of cleaning member 44 and the second type of cleaning member 43 have different cleaning effects. Cleaning methods include cleaning actions such as scraping, wiping, and sweeping, as well as cleaning methods such as chemical cleaning and ultrasonic cleaning, which are classified according to different cleaning tools.

[0029] In some specific embodiments, the first type of cleaning member 44 and the second type of cleaning member 43 are made of different materials, so that the cleaning effects of the first type of cleaning member 44 and the second type of cleaning member 43 are different. The material includes hardness, surface roughness, hydrophilicity, oil adsorption, etc. Among them, the surface roughness of the material directly affects the adhesion of the cleaning agent and the removal of dirt. The rough surface may be more likely to hide dirt, so a stronger cleaning method or a longer cleaning process is required. The surface of the hydrophilic material is easy to contact and wet with water, which helps wetting and dirt removal during the cleaning process. The hydrophobic surface is not easily wetted by water, and special cleaning agents or treatment methods may be required to achieve a good cleaning effect. The resistance of the material to the chemical components in the cleaning agent will affect the cleaning effect. If the material is easy to react chemically with the cleaning agent, it may cause surface damage or poor cleaning effect.

[0030] In some specific embodiments, the main body 1 is used to apply a first force to the surface to be cleaned through the first type of cleaning member 44 and a second force to the surface to be cleaned through the second type of cleaning member 43, and the first force is different from the second force so that the cleaning effects of the first type of cleaning member 44 and the second type of cleaning member 43 are different. The cleaning unit 2 is negatively adsorbed onto the surface to be cleaned, and the first type of cleaning member 44 and the second type of cleaning member 43 are respectively attached to the surface to be cleaned and exert pressure on the surface to be cleaned. When the first type of cleaning member 44 and the second type of cleaning member 43 are made of the same material, different forces will produce different cleaning effects. For example, the first type of cleaning member 44 and the second type of cleaning member 43 are both brushes. When the first type of cleaning member 44 exerts a greater force on the surface to be cleaned, the first type of cleaning member 44 has a better cleaning effect.

[0031] In some specific embodiments, the main body 1 drives the first type cleaning member 44 and the second type cleaning member 43 to rotate respectively, so that the rotation speeds of the first type cleaning member 44 and the second type cleaning member 43 are independently controlled, so that the cleaning effects of the first type cleaning member 44 and the second type cleaning member 43 are different. By controlling the rotation speeds of the first type cleaning member 44 and the second type cleaning member 43, the cleaning effects of the two can be changed. When the first type cleaning member 44 and the second type cleaning member 43 are made of the same material, the faster the rotation speed, the greater the number of times or area cleaned in the same time, and the better the cleaning effect.

[0032] In some specific embodiments, the first type of cleaning member 44 and the second type of cleaning member 43 have different hardnesses and can clean different types of stains. In addition, the first type of cleaning member 44 will perform pre-cleaning first, and the second type of cleaning member 43 will perform secondary cleaning after the pre-cleaning is completed. The two cleanings can greatly improve the cleaning effect. When the second type of cleaning member 43 is a cleaning cloth, the first type of cleaning member 44 with relatively large hardness will have a relatively good cleaning effect on stubborn stains, and then assist the flexible cleaning of the second type of cleaning member 43, which can significantly improve the cleaning effect of the cleaning machine on stubborn stains.

[0033] In some specific embodiments, the cleaning unit 2 is further provided with a driving assembly and a cleaning disc 4 connected to each other, and the driving assembly is used to drive the cleaning disc 4 to rotate so as to realize the mobile cleaning of the cleaning machine. Figure 1 shown.

[0034] In this application, the cleaning unit 2 is used to clean the surface to be cleaned. It is a component that performs the cleaning task and needs to be adsorbed onto the surface to be cleaned by negative pressure. The main body 1 is the structural part of the cleaning machine except the cleaning unit 2, on which the necessary modules such as the negative pressure device 5, the control unit, and the power supply are arranged. The number of cleaning units 2 is at least two to ensure that the cleaning machine can move forward stably. Figure 1 An example diagram of a cleaning machine with two cleaning units 2 is given.

[0035] In some specific embodiments, the driving assembly includes a driving portion 6 and a walking disk 3, and the walking disk 3 is connected to the driving portion 6 for rotating under the drive of the driving portion 6. The walking disk 3 is connected to the cleaning disk 4 for driving the cleaning disk 4 to rotate. In a common embodiment, at least two cleaning units 2 are provided, and the central axes of at least two walking disks 3 are inclined relative to the central axis of the main body 1, and the rotation directions of the two walking disks 3 are opposite to realize the rotational movement of the two cleaning units. Each cleaning unit 2 includes a cleaning disk 4 and a walking disk 3, and the number of cleaning disks 4 is equal to that of walking disks 3, that is, one cleaning disk 4 corresponds to one walking disk 3. The walking disk 3 is rotatably connected to the main body 1; an air groove that can form an adsorption space is provided in the cleaning disk 4. The cleaning disk 4 and the walking disk 3 are as shown in the attached figure. Figure 1 As shown, the cooperation of the two can enable the accommodating groove 7 to form an airway.

[0036] The cleaning machine needs to control the negative pressure adsorption of each cleaning unit 2 to the surface to be cleaned. In addition, each cleaning unit 2 is pre-set with an air path for the circulation of negative pressure airflow, and the negative pressure device 5 in the main body 1 is used to draw negative pressure on each air path so that the cleaning unit 2 is adsorbed to the surface to be cleaned under the action of air pressure. Under the adsorption of the negative pressure device 5, a closed space is formed between the cleaning machine and the surface to be cleaned, and the closed space includes the air path space inside the cleaning machine and the space between the cleaning machine and the surface to be cleaned. A walking disc 3 is provided in the cleaning unit 2, and the walking disc 3 is connected to a driving part 6 such as a motor, and rotates under the drive of the motor, thereby driving the rotation of the entire cleaning unit 2, and the rotation of multiple cleaning units 2 jointly realizes the movement of the cleaning machine. In some specific embodiments, the walking disc 3 is located in the central area of ​​the cleaning unit 2.

[0037] In some specific embodiments, the cleaning disk 4 includes an inner disk 42 and an outer disk 41, the inner disk 42 is connected to the outer disk 41 by snapping, and the outer disk 41 is connected to the driving assembly; the first type of cleaning member 44 is located on the outer disk 41, and the second type of cleaning member 43 is located on the inner disk 42. The connection relationship between the inner disk 42 and the outer disk 41 is as shown in the attached figure. Figure 2and attached Figure 3 As shown. In the present application, both the first type of cleaning member 44 and the second type of cleaning member 43 need to contact the surface to be cleaned, so a special structure is required to integrate the cleaning member into the cleaning machine. Exemplarily, the second type of cleaning member 43 uses a cleaning cloth, which is sleeved on the inner disk 42, and the inner disk 42 is fixed to the outer disk 41. When the outer disk 41 rotates, it drives the inner disk 42 to rotate, thereby achieving the effect of rotating wiping. In some embodiments, the inner disk 42 is detachably connected to the outer disk 41, and the outer disk 41 is detachably connected to the drive assembly, the first type of cleaning member 44 is detachably connected to the outer disk 41, and the second type of cleaning member 43 is detachably connected to the inner disk 42, and the various parts of the structure are connected in a detachable form to facilitate replacement and maintenance.

[0038] In some specific embodiments, the first type of cleaning member 44 includes a brush and / or a scraper; and / or the second type of cleaning member 43 includes a flexible cleaning cloth. Figure 2 A schematic diagram of the first type of cleaning member 44 as a scraper is given, and Figure 3 A schematic diagram of the first type of cleaning member 44 being a brush is provided. Brushes and scrapers are harder than cleaning cloths, and can wipe off stains adhering to the surface to be cleaned, and have a better cleaning effect on stubborn stains. The second type of cleaning member 43 generally uses a flexible cleaning cloth, which can withstand greater mechanical forces and can gently wipe off stains. Moreover, a flexible cleaning cloth usually has good water absorption, and can better absorb and remove stains, thereby reducing the possibility of stain residue. In addition, a flexible cleaning cloth is reusable, simple and convenient to replace, and has a low cost of use.

[0039] In some specific embodiments, the outer disk 41 is provided with a receiving groove 7, the inner disk 42 is located in the receiving groove 7 and is engaged with the receiving groove 7, and the first type of cleaning member 44 is located outside the receiving groove 7. Figure 3 As shown. A receiving groove 7 is provided on the outer disk 41 to facilitate the disassembly and assembly between the inner disk 42 and the outer disk 41. In practical applications, the outer disk 41 and the inner disk 42 can be connected by snapping only by inserting the inner disk 42 coated with the second type cleaning member 43 into the receiving groove 7. When the second type cleaning member 43 needs to be replaced or cleaned, the inner disk 42 can be replaced only by taking it out of the receiving groove 7. The receiving groove 7 needs to be located inside the first type cleaning member 44 to ensure that the first type cleaning member 44 is located outside the second type cleaning member 43 so that the first type cleaning member 44 can be pre-cleaned before the second type cleaning member 43.

[0040] Regarding the outer disk 41 and the first type of cleaning member 44, a fixed connection or a detachable connection can be selected. For example, the first type of cleaning member 44 is a brush, which is fixedly integrated on the edge of the outer disk 41, or embedded in the outer disk 41 to achieve a detachable connection. In some specific embodiments, a connector 9 is provided on the outer disk 41, and the first type of cleaning member 44 is detachably connected to the connector 9, and the connector 9 is located outside the receiving groove 7. The connector 9 is responsible for connecting the first type of cleaning member 44 and the outer disk 41, and the connection method of the connector 9 and the first type of cleaning member 44 and the outer disk 41 is not limited. Figure 4 In the embodiment, the connecting member 9 is a groove 8 structure, into which the first type of cleaning member 44 can be snapped.

[0041] In some specific embodiments, the first type of cleaning member 44 includes pores on the outer disk 41 and hair bodies in the pores, and the hair bodies and pores together constitute a brush for cleaning; the pores are distributed on the periphery of the inner disk 42, which is equivalent to the connecting member 9 for connecting the first type of cleaning member. The connecting member 9 is a structure of the pores as shown in the attached figure. Figure 5 As shown. In actual application, multiple pores can be punched on the edge of the outer disk 41, and the hair body can be fixed into the pores to obtain a brush. Since the bristles of the brush are harder, they can better deal with stubborn stains and remove the stains by physical friction. In addition, the bristles of the brush are dense, which can clean a large area of ​​dirt and dust faster, thereby improving cleaning efficiency.

[0042] In some specific embodiments, the first type of cleaning member 44 includes a scraper seat a1 and a plurality of scraper bodies a2 located on the scraper seat a1, and there is a gap between each scraper body a2. Figure 6 As shown. The scraper body a2 is made of a deformable soft rubber material. Since there are gaps between the scraper body a2, the scraper body a2 is endowed with a certain elasticity. When in use, the scraper body a2 will use its own hardness to wipe off stubborn stains, and will not cause wear or scratches to the surface to be cleaned due to its elasticity.

[0043] In some specific embodiments, the drive assembly extends a drive shaft toward the outer disk 41, and a connecting structure 45 is provided on the outer disk 41, the connecting structure 45 is engaged with the drive shaft, and the receiving groove 7 is located outside the connecting structure 45. The connecting structure 45 is a structure on the outer disk 41 for connecting the drive assembly, and the connecting structure 45 and the drive assembly are detachably connected, which is convenient for maintenance and replacement. In some specific embodiments, the connecting structure 45 includes an inner side wall 451, an outer side wall 452, and a connecting body 1 respectively connecting the inner side wall 451 and the outer side wall 452; the inner side wall 451 is provided with a plurality of grooves 8 for engaging the drive shaft; the outer side wall 452 is a side wall of the receiving groove 7. Exemplarily, a first side wall is provided on the outer edge of the outer disk 41, and the first type of cleaning member 44 is located on the first side wall, and the first side wall and the outer side wall 452 constitute the receiving groove 7.

[0044] In some specific embodiments, a plurality of blocking arms 453 are distributed on the connecting body 1, one end of the blocking arm 453 is connected to the inner wall 451, and the other end is connected to the outer wall 452; two adjacent blocking arms 453, the inner wall 451, and the outer wall 452 together form a blocking space 454, and the blocking space 454 is used to reduce the airflow loss. The structure of the blocking space 454 and the blocking arm 453 is shown in the attached figure. Figure 2-5 The blocking space 454 is equivalent to the space formed by the connection body 1 protruding toward the surface to be cleaned. When the cleaning unit 2 is adsorbed to the surface to be cleaned to form a closed space, the airflow passing through the blocking space 454 will be blocked, thereby reducing the loss of airflow.

[0045] The main body 1 evacuates the enclosed space in each cleaning unit 2 through the negative pressure device 5, and the negative pressure in the enclosed space converges to the negative pressure device 5 along the air path inside the cleaning machine. When the negative pressure in the enclosed space reaches the preset adsorption value, the cleaning unit 2 can be firmly adsorbed onto the surface to be cleaned. In addition, during the cleaning movement process, each enclosed space will be monitored in real time by the negative pressure detection device on the main body 1. When multiple cleaning units 2 are simultaneously negatively adsorbed onto the surface to be cleaned, the host can control the rotation of the cleaning unit 2 to realize the movement of the cleaning machine and complete the mobile cleaning of the surface to be cleaned. Among them, the host controls the rotation of the cleaning unit 2 to realize the movement of the cleaning machine, which can be that the host controls at least two cleaning units 2 to rotate simultaneously, so that the cleaning machine moves in a straight line or a straight line-like manner. It can also be that the host controls multiple cleaning units 2 to rotate alternately, so that the cleaning machine moves in a swinging manner.

[0046] In the cleaning machine, a plurality of negative pressure chambers are provided in the main body 1, each of which is connected to a closed space in a cleaning unit 2; the negative pressure device 5 is used to evacuate the negative pressure chamber and the closed space connected to the negative pressure chamber; the negative pressure detection device is used to detect the negative pressure of the negative pressure chamber to obtain the negative pressure of the closed space.

[0047] The present application provides a cleaning machine that performs multiple cleanings with the help of two cleaning parts with different cleaning effects, which can significantly improve the cleaning effect of the cleaning machine on stubborn stains without affecting the cleaning effect of the cleaning machine on ordinary stains. It meets different types of stains and cleaning needs, significantly improves cleaning efficiency, reduces the number of times the cleaning cloth is replaced, and improves the overall cleaning effect.

[0048] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, device, article or method including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, device, article or method. In the absence of further restrictions, an element defined by the sentence "includes a ..." does not exclude the presence of other identical elements in the process, device, article or method including the element.
