Detailed Description

In the following description, numerous implementation details are set forth in order to provide a more thorough understanding of the present invention. It should be understood, however, that these implementation details should not be used to limit the invention. That is, in some embodiments of the invention, details of these implementations are not necessary. In addition, for the sake of simplicity, some conventional structures and elements are shown in the drawings in a simple schematic manner.

Please refer to fig. 1 and fig. 2 simultaneously. Fig. 1 is a schematic front view of a touch device 100 according to an embodiment of the present invention. Fig. 2 is a functional block diagram of the touch device 100. First, the touch device 100 includes a body 110, wherein the body 110 is a mechanical device having a touch indication function or a press indication function, such as a touch interface or a touch button, and therefore the body 110 at least has a touch surface 111 for a user to operate. Even in the present invention, the body 110 is not limited to a single mechanical device, but may refer to a plurality of mechanical devices connected to each other. In addition, the touch device 100 further includes a sensing unit 120, a processing unit 130 and a liquid spraying unit 150 carried on the body 110, and the processing unit 130 is connected to the sensing unit 120 and the liquid spraying unit 150.

In this embodiment, the processing unit 130 can control the sensing unit 120 to detect an action indication of a user in front of the touch device 100, and then the processing unit 130 controls the liquid spraying unit 150 to spray the cleaning liquid onto the touch surface 111 according to the action indication. By using the preset action indication, the user can instruct the liquid spraying unit 150 to clean the touch surface 111 without touching the touch surface 111, so that the touch device 100 achieves the health management effect of preventing germs from spreading through both hands.

The motion indication in the present invention may be a continuous motion (e.g. nodding and shaking) or a static posture, which is accomplished by the user using the limbs, but the present invention is not limited thereto. The processing unit 130 controls the liquid spraying unit 150 to spray the cleaning liquid according to a predetermined cleaning function after recognizing the motion instruction. For example, the user's nodding motion may be preset to indicate spraying of cleaning liquid or shaking motion to indicate not spraying of cleaning liquid. When the sensing unit 120 detects the nodding motion of the user, the processing unit 130 further controls the liquid spraying unit 150 to spray the cleaning liquid toward the touch surface 111.

In some embodiments of the present invention, the sensing unit 120 includes an image sensor for capturing the action indication of the user, and the processing unit 130 further controls the liquid spraying unit 150 to spray the cleaning liquid according to the result of analyzing the action indication. Specifically, the touch surface 111 may be an operation surface of a touch panel, or a pressing surface of a key input device, but the present invention is not limited thereto. The sensing unit 120 may be a Charge-Coupled Device (CCD) or a Complementary Metal-Oxide-Semiconductor (CMOS) Device for sensing the motion or distance of the user to capture the motion indication or the position of the user, but the present invention is not limited thereto. The touch device 100 may further be equipped with an infrared light emitting diode, and the sensing unit 120 may include an infrared sensor, for example, a Position-Sensitive Detector (PSD) for sensing a Position of a user, but the invention is not limited thereto.

The Processing Unit 130 may be a Central Processing Unit (CPU), a controller or other computing device with computing function, and cooperates with software, firmware or other hardware to assist computing and identify the image or image of the motion indication captured by the sensing Unit 120, so as to determine the motion indication of the user, but the invention is not limited thereto.

In some embodiments of the present invention, the liquid spraying unit 150 includes at least one nozzle 151 and a pump body 155. The pump body 155 is connected to the nozzle 151 via the flow channel 154, wherein the pump body 155 is used to deliver the cleaning liquid inside to the nozzle 151, so that the nozzle 151 sprays the cleaning liquid.

Specifically, the nozzle 151 may be, for example, an atomizing nozzle to facilitate large-area spraying of the cleaning liquid. The pump body 155 pressurizes the cleaning liquid contained therein, and then delivers the cleaning liquid to the nozzle 151. The flow channel 154 may include a channel path or a conduit path for transporting a liquid, and is not limited to a physical conduit configuration. In addition, the liquid flow channel 154 may be a plastic pipe or a metal pipe, which is not limited by the present invention.

Specifically, the pump body 155 may be a spirit pump, and the contained cleaning liquid is alcohol. Therefore, the alcohol pump can pressurize the contained alcohol and deliver the alcohol to the nozzle 151 through the liquid flow channel 154, and the nozzle 151 further sprays the alcohol to the touch surface 111 for sterilization.

In some embodiments of the present invention, the liquid spraying unit 150 further includes a solenoid valve 153 disposed between the nozzle 151 and the pump body 155 and located in the liquid flow channel 154. The solenoid valve 153 can control the flow of the cleaning liquid between the nozzle 151 and the pump body 155, even completely block the flow of the cleaning liquid to the nozzle 151, so as to rapidly prevent the liquid from flowing out in an emergency.

In some embodiments of the present invention, the body 110 includes a housing 113 covering a peripheral area of the touch surface 111, and the housing 113 shields the nozzle 151 at least in an axial direction perpendicular to the touch surface 111. Therefore, when the user faces and operates on the touch surface 111, the presence of the nozzle 151 is difficult to be found from the appearance, thereby maintaining the aesthetic appearance of the touch device 100.

In some embodiments of the present invention, the touch device 100 includes two nozzles 151 respectively disposed on two corresponding sides of the touch surface 111. Specifically, the two nozzles 151 are equally high and configured to spray the cleaning solution toward the center of the touch surface 111 so as to uniformly spray the cleaning solution toward the touch surface 111, but the present invention is not limited thereto.

In some embodiments of the present invention, the touch device 100 further comprises a communication unit 170 connected to the processing unit 130, and the liquid spraying unit 150 further comprises a monitor 157 for detecting the cleaning liquid inside the pump body 155, when the cleaning liquid inside the pump body 155 is lower than the preset value, the processing unit 130 controls the communication unit 170 to transmit a reminding message to an external device, so as to remind the staff of replenishing the cleaning liquid.

Specifically, the communication unit 170 may include a bluetooth transmitter or a wireless network transmitter to facilitate the remote transmission of the reminding message. The monitor 157 may be a weight sensor or a pressure sensor to detect changes in the weight or pressure of the cleaning fluid in the pump body 155. The external device may be, for example, a smart phone, a desktop computer, a notebook computer, or the like, which is not limited to the above. Therefore, the user can preset a preset weight threshold or hydraulic threshold, and when the monitor 157 detects that the weight or pressure of the cleaning solution is lower than the preset weight threshold or hydraulic threshold, the processing unit 130 controls the communication unit 170 to transmit a reminding message to an external device to remind the staff to replenish the cleaning solution. In addition, the reminding message can be a text reminding message, a voice reminding message or an imaging reminding message, so as to remind the staff to replenish the cleaning solution.

In some embodiments of the present invention, the touch device 100 further includes an output unit 180 connected to the processing unit 130, wherein when the sensing unit 120 detects that the user is close to the touch device 100, the output unit 180 can prompt the instruction content corresponding to the action indication and send out the inquiry content for cleaning the touch surface 111.

Specifically, the output unit 180 may include a display panel (e.g., a display panel with a touch function) or a speaker (e.g., a speaker). Therefore, when the touch device 100 detects that the user approaches, the output unit 180 may prompt the user with the preset operation instruction description content and the corresponding cleaning function in a text, graphic or voice manner, so that the user can quickly understand and operate the operation.

In some embodiments of the present invention, the touch device 100 further includes a power supply unit 190 electrically connected to the sensing unit 120, the processing unit 130 or the liquid spraying unit 150, so as to provide power to the sensing unit 120, the processing unit 130 or the liquid spraying unit 150. In addition, the power supply unit 190 may also be electrically connected to the output unit 180 and the communication unit 170 to provide power. Specifically, the power supply unit 190 may be a battery assembly supported on the body 110, but the power supply unit 190 may also include an electric wire and a plug for electrically connecting to an external power source, which is not limited by the present invention.

Please refer to fig. 3. Fig. 3 is a flowchart illustrating a control method 200 for operating the touch device 100 according to some embodiments of the present invention. The control method 200 includes steps S210 to S250. The control method 200 starts at step S210, in which the processing unit 130 controls the sensing unit 120 to continuously detect whether a user approaches the front of the touch device 100. When the sensing unit 120 detects that the user approaches the touch device 100, the control method 200 proceeds to step S220. The sensing unit 120 and the processing unit 130 are described in detail in the previous paragraphs, and are not described herein again.

In step S220, the output unit 180 prompts the explanatory content corresponding to the action instruction and issues an inquiry content for cleaning the touch surface. As mentioned above, the output unit 180 may include a display panel or a speaker, and further prompt the preset action indication and the corresponding description of the cleaning function in a text, image or voice manner, so that the user can quickly understand and operate the touch device 100. For example, when the user indicates spraying the cleaning liquid to the sensing unit 120 with an action indication (e.g., nodding), the control method 200 proceeds to step S230. When the user indicates to the sensing unit 120 with an action indication (e.g. shaking head) that the cleaning liquid is not to be sprayed, the control method 200 ends at step S220.

In step S230, the liquid spraying unit 150 sprays cleaning liquid to the touch surface 111. The touch surface 111 and the liquid spraying unit 150 are described in detail in the previous paragraphs, and are not described herein again. When step S230 ends, it may optionally proceed to step S240. In some embodiments of the present invention, when step S230 is finished, the output unit 180 issues a prompt message, such as a prompt message for extracting a tissue, to remind the user to wipe the touch surface 111 with the tissue. The output unit 180 is described in detail in the previous paragraphs, and will not be described herein.

In step S240, the monitor 157 of the liquid spraying unit 150 detects the cleaning liquid contained in the liquid spraying unit 150. The monitor 157 is described in detail in the previous paragraphs and will not be described herein. When the monitor 157 detects that the weight or pressure of the cleaning liquid is lower than the preset weight threshold or hydraulic pressure threshold, the process proceeds to step S250.

In S250, the processing unit 130 controls the communication unit 170 to transmit a reminding message to an external device to remind a worker to replenish the cleaning liquid to the liquid spraying unit 150. The communication unit 170 or the external device is described in detail in the previous paragraphs, and will not be described herein.
