Detailed Description

To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are given in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, this embodiment is provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

The embodiment provides a window cleaning machine, and the window cleaning machine in the embodiment adopts a method that a fan inside the machine generates negative pressure on the bottom surface of a sweeper and is adsorbed on a working surface.

Referring to fig. 1, a handle 10 for a user to hold is provided above the window cleaning machine in the present embodiment, a key switch SW is provided on an upper surface of the handle 10, and a touch switch P1 is provided on a lower surface of the handle 10; when the user holds the handle 10 with a hand, the hand can contact the touch switch P1 and trigger the touch switch P1; the position of the touch switch P1 makes it difficult to be triggered by mistake when the user is not holding the handle 10.

Referring to fig. 2, the control system of the window cleaning machine in the present embodiment includes a control module 21, configured to control the operation of the window cleaning machine, where the control module 21 is connected to the fan 24 and can control the operating state of the fan 24; the touch control device is also connected with a key switch circuit 22 and a touch switch circuit 23, the key switch circuit 22 is provided with a key switch SW, and the key switch circuit 22 sends a key signal to the control module 21 after the key switch SW is pressed down; the touch switch circuit 23 has a touch switch P1, and triggers the touch switch P1 to transmit a touch signal to the control module 21 from the touch switch circuit 23.

Referring to fig. 3, a schematic diagram of the key switch circuit 22 includes a mechanical key switch SW; the key switch SW is a switch that is closed only when pressed by an external force and is in an open state when not pressed by an external force. The output end KEY _ BUTT of the KEY switch circuit is connected with the control module 21, and the KEY switch circuit 22 generates high and low level signals respectively when the KEY switch SW is released and pressed. When the KEY switch SW is pressed, the KEY switch circuit output end KEY _ BUTT outputs a KEY signal to the control module 21.

Referring to fig. 4, a schematic diagram of the TOUCH switch circuit 23 includes a TOUCH switch P1, the TOUCH switch P1 is located on a lower surface of the handle 10 of the window cleaning machine, and when a user holds the window cleaning machine, an analog TOUCH signal is generated, and the analog TOUCH signal is processed by the TOUCH sensor U1 and then output to the control module 21, and the TOUCH signal is sent to the control module 21 through the TOUCH switch circuit output terminal TOUCH _ KEY.

Referring to fig. 5, in the process of opening the window cleaner, the fan 24 is in the off state, connected to the power supply, the host circuit is powered on, and the control module 21 is initialized. If the user presses the key switch SW while not holding the handle 10 of the window cleaning machine, the touch switch P1 cannot be triggered, and the control module 21 will not control the fan 24 to be turned on. If the user presses the key switch SW and holds the handle 10 of the window cleaning machine with a hand, the palm of the user triggers the touch switch P1 to generate a touch signal, the control module 21 detects the key signal and the touch signal at the same time, and at this time, the control module 21 controls the fan 24 to be turned on, so that the user can safely adsorb the window cleaning machine on the working surface.

Referring to fig. 6, during the closing process of the window cleaning machine, that is, when the fan 24 is in the on state, the window cleaning machine is attached to the working surface, if the user presses the key switch SW while not holding the handle 10 of the window cleaning machine, that is, the touch switch P1 is not triggered, the control module 21 will not control the fan 24 to be turned off. If the user presses the key switch SW and holds the handle 10 of the window cleaning machine with a hand, the hand of the user triggers the touch switch P1 to generate a touch signal, the control module 21 detects the key signal and the touch signal at the same time, at this time, the fan 24 is controlled to be turned off to stop adsorption, and the user can take down the window cleaning machine.

In this way, the working state of the fan 24 can be guaranteed not to change under the condition that a user does not hold the window cleaning machine handle 10, so that the condition that a person unfamiliar with window cleaning machine operation changes the working state of the fan when the person does not hold the window cleaning machine in a hand, and the window cleaning machine falls accidentally is avoided.

The above-described embodiments are merely illustrative of one embodiment of the present invention, which is described in more detail and detail, but not to be construed as limiting the scope of the patent. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
