DETAILED DESCRIPTION

[0044] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0045] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0046] like Figure 1-Figure 7As shown, the present invention provides a vacuum cleaner for student engineering practice, including: a base 1, a mounting seat 2, a material box 3 and an air extraction device; the air extraction device is a commercially available fan or an existing technology used in a commercially available vacuum cleaner for extracting dust and impurities. The base 1 is provided with wheels, so that it is convenient for users to push the vacuum cleaner or facilitate the autonomous movement of the vacuum cleaner. See the following embodiment for details. The mounting seat 2 is arranged on the base 1, and is used to accommodate structures such as a power source, an air extraction device, and a controller, and to provide support for the installation of the material box 3. The air extraction device is arranged in the mounting seat 2, and the material box 3 is detachably mounted on the mounting seat 2, and the material box 3 is connected to the cleaning head 4 through a pipeline. The detachable connection between the material box 3 and the mounting seat 2 can facilitate the cleaning of the material box 3. The air extraction device is connected to the cleaning head 4 arranged on the base 1 through the material box 3 arranged on the mounting seat 2. The mounting seat 2 is provided with an identification module 5, which faces the direction of the cleaning head 4. The mounting seat 2 is provided with a controller. The air extraction device and the identification module 5 are both electrically connected to the power supply through the controller. The identification module 5 is usually an image acquisition device for identifying stains or impurities adhering to the ground. The power supply is usually a battery arranged in the mounting seat 2. The mounting seat 2 is provided with an interface. When the user uses manual cleaning, an extension rod can be arranged in the interface so that it can be used as an ordinary vacuum cleaner. In order to make the vacuum cleaner intelligent, the mounting seat 2 is usually provided with a first driving device, which is connected to the wheel for driving the wheel to rotate, and the first driving device is electrically connected to the controller. In this way, the vacuum cleaner can be made intelligent, and instructions can be issued to the controller through a mobile phone terminal or a PC terminal, and the controller can be program edited, etc., thereby realizing the intelligence of the vacuum cleaner. It should be noted that the controller is a general term for the existing technology of realizing intelligent control such as a signal transceiver, a control chip, etc.

[0047] The working principle and beneficial effects of the above technical solution: Through the design of the above structure, the identification module 5 can be used to identify ground stains or impurities, and the vacuum cleaner can execute repeated cleaning instructions for stubborn stains or impurities, and the identification module 5 can realize autonomous movement and obstacle avoidance of the vacuum cleaner, making the vacuum cleaner more intelligent.

[0048] After the identification module 5 is provided to enable the vacuum cleaner to have the functions of stain identification and obstacle avoidance, and the relatively mature controller and control instructions on the market are adopted to realize the repeated cleaning and moving functions of the vacuum cleaner, it is necessary to consider that the difference between the vacuum cleaner and the sweeping robot is not only that the size is quite different, but also that the cleaning ability is different. The sweeping robot can remove the stubborn stains on the ground by a rotating brush, while the vacuum cleaner does not have the ability to remove stubborn stains. Therefore, in order to increase the stubborn stain removal function, a mounting surface is provided at the front end of the cleaning head 4, and there is an angle a between the mounting surface and the ground, such as Figure 2As shown, the inclined angle can be used as a space to accommodate the cleaning wheel 6 and the supporting leg 7, the cleaning wheel 6 is arranged on the mounting surface, and the second driving device connected to the cleaning wheel 6 is arranged in the cleaning head 4, the second driving device is used to adjust the position of the cleaning wheel 6, drive or prevent the cleaning wheel 6 from rotating. Usually, after identifying the stubborn stains, the vacuum cleaner will move above the stains and let the cleaning wheel 6 be above the stubborn stains, and then the controller will move the cleaning wheel 6 downward to abut the stubborn stains or the ground through the second driving device, and then the cleaning wheel 6 will reverse (when the cleaning wheel 6 reverses, the torque is less than the torque of the wheel to avoid affecting the reciprocating movement of the vacuum cleaner), or it will remain stationary, and the vacuum cleaner will reciprocate so that the cleaning wheel 6 can rub the stubborn stains (similar to erasing pencil marks with an eraser), and the second driving device is electrically connected to the controller. In order to prevent the second driving device from burning out due to excessive friction when the cleaning wheel 6 is reversed or stationary to rub stubborn stains, the cleaning wheel 6 is composed of an inner core 61 connected to the second driving device, and an outer ring 62 arranged outside the inner core 61. The outer ring 62 is made of elastic material and is sleeved on the inner core 61 to form a connection similar to that of a tire and a wheel hub. The outer ring 62 is provided with an outer channel group 63, a middle channel group 64, and an inner channel group 65 that pass through both ends. The three channel groups are all ring-shaped and composed of a plurality of through holes, such as Figure 3 As shown, the outer ring 62 can have a larger deformation when rubbing stubborn stains. Because the vacuum cleaner is larger in size and the suction device is heavier than the sweeping robot, after being integrated on the base 1, the weight distribution will be uneven, and there is a problem of easy tipping. Therefore, when setting the mounting base 2, the mounting base 2 can be slightly tilted toward the cleaning head 4, so that the center of gravity is located between the connecting shaft of the wheel and the cleaning head 4, as shown in FIG. Figure 1 As shown, because the material box 3 needs to be installed, the height of the vacuum cleaner will be relatively high and it is easy to tip over toward the cleaning head 4, so a connecting column is provided on the installation surface, and the bottom of the connecting column is threadedly connected to a supporting leg 7, and there is a certain distance between the supporting leg 7 and the ground to avoid affecting the movement of the vacuum cleaner and the contact between stubborn stains and the cleaning wheel 6.

[0049] If you want to make the vacuum cleaner intelligent, the first thing you want to solve is the problem of stain recognition and obstacle avoidance. Compared with the sweeping robot, the vacuum cleaner is larger in size and it is necessary to consider whether the passage height is sufficient. Since the cleaning wheel 6 is provided to clean the stubborn stains, it is necessary to identify the stubborn stains. Usually, it is necessary to consider the height and width of the stubborn stains. The height determines whether the stubborn stains can enter the bottom of the installation surface, and the width determines whether the cleaning wheel 6 can cover the stubborn stains at one time. Therefore, in this embodiment, the recognition module 5 includes an elevation module 51, a bottom recognition module 52, a top recognition module 53 and a horizontal recognition module 54;

[0050] An elevation module 51 is used to identify whether the path height allows the vacuum cleaner to pass through;

[0051] The bottom recognition module 52 is used to recognize whether there is a stain on the ground and provide the controller with the color information of the stain and the coordinate information of the bottom of the stain; it determines whether it is a stain by different color depths, similar to identifying the moving path of black in a robot racing game;

[0052] A top recognition module 53, for providing the coordinate information of the top of the stain to the controller;

[0053] The horizontal recognition module 54 is used to recognize whether there is an obstacle in front of the vacuum cleaner and provide the width coordinates of the stain to the controller. It should be noted that the above three modules can all be visual modules, such as the visual sensor of the Lego mechanical set.

[0054] The intelligent working process of the vacuum cleaner is as follows:

[0055] After the vacuum cleaner is started, the elevation module 51 and the horizontal recognition module 54 jointly collect images and determine whether there are obstacles and stains on the cleaning path;

[0056] When there are no obstacles or stains on the path, the vacuum cleaner continues to clean along the cleaning path;

[0057] When there are obstacles or stains on the path, the bottom recognition module 52, the top recognition module 53 and the horizontal recognition module 54 jointly collect images of the obstacles or stains, and judge the shape characteristics through the controller, and judge the color characteristics through the controller;

[0058] The shape feature and the color feature are fused to determine whether the object on the cleaning path is an obstacle or a stain;

[0059] If it is determined to be an obstacle, the vacuum cleaner will go around it;

[0060] If it is determined to be a stain, the controller will issue a reciprocating cleaning instruction to the vacuum cleaner;

[0061] During the first cleaning, the cleaning head 4 of the vacuum cleaner passes over the stain to suck the stain. According to the acquired coordinate values, the cleaning head 4 is controlled to pass over the stain to suck the stain. Then the vacuum cleaner returns to the position where the first cleaning was performed. The bottom recognition module 52, the top recognition module 53 and the horizontal recognition module 54 perform image acquisition again, as well as shape feature and color feature determination.

[0062] If the stain is removed, it continues to move along the cleaning path to complete the subsequent cleaning process;

[0063] If stains are still detected, perform a second cleaning;

[0064] When performing the second cleaning, the controller lowers the cleaning wheel 6 to contact the ground through the second driving device, and reverses the cleaning wheel 6 or stops the cleaning wheel 6 from rotating, and then the vacuum cleaner moves over the stain again and resets;

[0065] Perform stain identification again after resetting;

[0066] If the stain is removed, it continues to move along the cleaning path to complete the subsequent cleaning process;

[0067] If stains are still identified, the third cleaning is performed, and the third cleaning instruction is the same as the second cleaning instruction, and this cycle repeats until the Nth cleaning is performed;

[0068] After the Nth cleaning is completed, if stains are still identified, an abnormality report is sent to the terminal through the controller, and the stain is abandoned, and the vehicle continues to move along the cleaning path to complete the subsequent cleaning process.

[0069] Where N is the number of times set by the user through the terminal. If the stain still remains after multiple cleanings, it proves that the stain requires manual intervention for cleaning.
