New description: [New technical field] The present invention relates to a virtual wall device, and in particular to a virtual wall device for a vacuum cleaner. [Prior Art] The larger the horsepower of the vacuum cleaner, the stronger the suction force is. However, the vacuum cleaner is relatively more power-hungry. Generally, the vacuum cleaner consumes about 180 watts (W) to 300 watts (W), which is much higher than a typical electric fan, so it can absorb dust. Vacuum cleaners are usually based on suction and dry vacuum cleaners. According to the average person's preference, products with small size, quietness, power saving and high suction power are most popular among consumers. At present, vacuum cleaners generally sold on the market are cleaned by a fixed rotation speed. Some vacuum cleaners are equipped with a multi-stage suction adjustment device's artificially determining the dirty level of the floor to adjust the power of the vacuum cleaner motor. However, it does not have the function of high intelligence to judge the dirty level of the floor, and there are still inconveniences in use. . In addition, commercially available vacuum cleaners require manual operation when vacuuming, and a certain area is cleaned by manual operation; operation during the entire cleaning process is quite labor intensive. ^The traditional vacuum cleaner can't automatically detect the wall, obstacles, steps or 疋 to limit the area where the vacuum cleaner is walking. This is easy to cause damage to the vacuum cleaner due to the collision of the vacuum cleaner. Schematic diagram of M321281. Referring to FIG. 1 , FIG. 2 and FIG. 3 , the virtual wall device 1′′ of the vacuum cleaner of the present invention comprises a virtual wall transmitting circuit 11〇 and a virtual wall receiving circuit 120. The virtual wall transmitting circuit 110 includes an infrared light. The transmitter lu is coupled to a resistor 112. When the virtual wall transmitting circuit 11 is disposed in a vacuum cleaner 2, an infrared ray is emitted from the infrared ray emitter 111, and an effective distance of about 5 meters is emitted to establish a virtual wall. The virtual wall receiving circuit 120 is configured to receive the signal emitted by the infrared emitter 111 of the virtual wall transmitting circuit 110. The infrared light emitted by the virtual wall transmitting circuit 11 投 is projected to a preset distance (the effective distance is up to 5 meters), and the user can use this function to set the forbidden area. When the vacuum cleaner 300 travels through the area (ie, the virtual wall 200), and the virtual wall receiving circuit 12 receives the infrared signal emitted by the virtual wall transmitting circuit 110, the vacuum cleaner 3 automatically determines that the area is prohibited. The passing area is then automatically turned to the originally set angle (this embodiment is set to an angle of 90 degrees) to proceed. Therefore, the virtual wall device of the vacuum cleaner of the present invention can emit an infrared light beam to a restricted area by the infrared emitter 111. When the vacuum cleaner 300 approaches the restricted area (virtual wall), the virtual wall receiving circuit 120 receives the virtual transmitting circuit. When the signal transmitted by 110 is automatically turned to the originally set angle, the vacuum cleaner 300 is prevented from being damaged by the collision of the wall surface or the obstacle. Although the present invention has been disclosed in an embodiment, it is not intended to limit the scope of the present invention. Any one skilled in the art can make various changes and retouchings without departing from the spirit and scope of the present invention. The scope of protection is subject to the definition of the scope of the patent application.
