The utility model has the following advantages: the acceleration sensing unit detects whether the indoor space is used by the user or has just been used, so that the processing unit uses the cleaning agent at a time interval at least corresponding to the third predetermined value. Squirting for the purpose of performing automatic cleaning efficiently.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIG. 1, a first embodiment of the automatic cleaning device of the present invention is applicable to an indoor space. The indoor space includes an entrance and exit for providing a door panel 91. The door panel 91 includes a door handle 92, and the door handle 92 is disposed on the door handle 92. The door panel 91 is adjacent to one side of the indoor space. For example, the indoor space is a toilet in a public place. When a user wants to leave the restroom, the user touches the door handle 92 with a hand to push the door panel 91 away.

The automatic cleaning device includes an ambient light source sensing unit 3, an acceleration sensing unit 2, a spray mechanism 9, a driving unit 6, a consumable replacement detecting unit 7, an input unit 5, a temperature sensing unit 4, A display unit 8 and a processing unit 1.

The ambient light source sensing unit 3 is electrically connected to the processing unit 1 and detects the brightness of the ambient light source in the indoor space to generate an ambient light source value, and transmits the ambient light source value to the processing unit 1. The acceleration sensing unit 2 is disposed on the door panel 91, and detects the acceleration of the door panel 91 when moving or rotating to generate an acceleration value, and electrically connects the processing unit 1 to transmit the acceleration value to the The processing unit 1.

Referring to Figures 1 and 2, in the present embodiment, the spray mechanism 9 houses a cleaning agent, and the cleaning agent is a disinfectant. The spray mechanism 9 is disposed on the door panel 91 and adjacent to the door handle 92. When the spray mechanism 9 is actuated, the spray mechanism 9 sprays the cleaning agent onto the door handle 92, for example, by spraying. The door handle 92 is sterilized. The driving unit 6 is electrically connected to the processing unit 1 to receive a driving signal, and drives a specific mechanical mechanism to drive the spraying mechanism 9 to operate. This particular mechanical mechanism is not limited to known techniques such as gear sets.

The consumable replacement detecting unit 7 is electrically connected to the processing unit 1. When the cleaning agent is replaced by the cleaning mechanism, the consumable replacement detecting unit 7 generates a replacement signal, and transmits the replacement signal to the Processing unit 1. For example, the consumable replacement unit includes a button that can be pressed to trigger the replacement signal after a worker replaces the cleaning agent of the spray mechanism 9. Alternatively, the button can be triggered to generate the replacement signal by the pressure of the contact between the container and other components of the spray mechanism 9 when the worker replaces a container for the detergent in the spray mechanism 9. , but not limited to this. In addition, the consumable replacement detecting unit 7 may further include a lock to ensure that only the worker operation can be provided while avoiding misuse by other users.

The input unit 5 receives an input signal to generate a preset parameter and electrically connects the processing unit 1 to transmit the preset parameter to the processing unit 1. For example, the input unit 5 can be a small keyboard or a touch screen, but not limited thereto. The worker inputs by the input unit 5 to generate the preset parameter, for example, 5000, to indicate that the cleaning agent of the spray mechanism 9 can be replaced by the drive unit 6 after the replacement. The cleaner was sprayed out 5,000 times.

The temperature sensing unit 4 is disposed on the door panel 91 adjacent to the door handle 92 and electrically connected to the processing unit 1 and fixedly and continuously detects temperature in a certain direction. When the user's hand is touching or adjacent to the door handle 92, the temperature sensing unit 4 detects that the body temperature of the user's hand is higher than the room temperature of the indoor space, and generates a temperature sensing signal, and The temperature sensing signal is transmitted to the processing unit 1. When the user's hand is not adjacent to the door handle 92, the temperature detected by the temperature sensing unit 4 is substantially equal to the room temperature of the indoor space, and thus the temperature sensing signal is not generated.

The processing unit 1 stores an available number of times to indicate the number of times the cleaning agent 9 can be ejected. When the processing unit 1 initially generates the preset parameter by the input unit 5, for example, the processing unit 1 equalizes the available number of times to the preset parameter. The processing unit 1 generates the drive signal based on the ambient light source value, the acceleration value, and the time from the last time the spray mechanism 9 ejects the detergent.

In more detail, when the processing unit 1 determines that the ambient light source value is greater than a third preset value, and the acceleration value is greater than a first preset value, and the time from the previous generation of the driving signal is greater than a second pre- When the value is set, the processing unit 1 generates the drive signal, and decrements the number of available times by one each time the drive signal is generated. In this embodiment, the second preset value is, for example, five minutes, but is not limited thereto. In addition, when the processing unit 1 receives the temperature sensing signal, the processing unit 1 does not generate the driving signal to prevent the spraying mechanism 9 from acting to spray the cleaning agent to the user's hand.

Moreover, when the available number of times is equal to zero, the processing unit 1 generates an alert signal. The display unit 8 is electrically connected to the processing unit 1 to receive the warning signal and display a warning message related to the warning signal, for example, indicating that the cleaning agent has run out. The processing unit 1 further controls the display unit 8 to display the preset parameter and the available number of times for the worker to view the operating status of the automatic cleaning device. In addition, it should be added that the display unit 8 can be covered by some mechanism design to ensure that it can be viewed only when the worker operates, but not limited thereto.

It should be particularly noted that in the embodiment, the automatic cleaning device includes the ambient light source sensing unit 3. In other embodiments, the automatic cleaning device may also omit the ambient light source sensing unit 3, that is, the processing unit 1 determines that the acceleration value is greater than the first preset value, and the time before the driving signal is generated. When the second preset value is greater than, the processing unit generates the driving signal.

In addition, in the embodiment, the ambient light source sensing unit 3, the acceleration sensing unit 2, the spray mechanism 9, the driving unit 6, the consumable replacement detecting unit 7, the input unit 5, and the temperature sensing The unit 4, the display unit 8, and the processing unit 1 are integrated in a single mechanism housing. In other embodiments, the acceleration sensing unit 2, the spraying mechanism 9, the driving unit 6, the consumable replacement detecting unit 7, the input unit 5, the temperature sensing unit 4, and the display unit may be 8. The processing unit 1 is integrated in a single mechanism housing, and the ambient light source sensing unit 3 (or other components of the automatic cleaning device) is independent of the mechanism housing, and is not limited thereto.

Referring to Figures 1 and 3, Figure 3 is a flow chart exemplarily illustrating steps S1 - S12 performed by the automatic cleaning device.

In step S1, the worker generates the preset parameter N by the input unit 5, and initially, the processing unit 1 loads the preset parameter N, so that the available number of times is equal to the preset parameter N, and then executes Step S2.

In step S2, the processing unit 1 responds with a replacement signal to determine whether the consumable is replaced, that is, whether the cleaning agent has been replaced. When the processing unit 1 receives the replacement signal, it is determined that the consumable has been replaced, and step S4 is performed again. When the processing unit 1 does not receive the replacement signal, it is determined that the consumable is not replaced, and step S3 is performed again.

In step S3, the processing unit 1 generates the warning signal, and controls the display unit 8 to display the warning message related to the warning signal to remind the worker that the consumable needs to be replaced, and then performs step S1.

In step S4, the ambient light source sensing unit 3 detects the ambient light source, and the processing unit 1 determines whether the ambient light source value is greater than the third preset value. When the ambient light source value is greater than the third preset value, it indicates that the indoor space is turned on, that is, the indoor space is in a working period. For example, if the restroom is open for use, step S6 is performed. When the ambient light source value is less than the third preset value, it indicates that the indoor space is not turned on, that is, the indoor space is in a non-working period, for example, the restroom is temporarily closed, and then step S5 is performed.

In step S5, the processing unit 1 controls the display unit 8 to display another warning message related to the non-working period, and then performs step S4.

In step S6, the acceleration sensing unit 2 performs motion detection or rotation detection of the door panel 91, and the processing unit 1 determines whether the acceleration value is greater than the first preset value. When the acceleration value is greater than the first preset value, it indicates that the door panel 91 is moved or rotated, that is, if the user has used or just used the indoor space, step S7 is performed. When the acceleration value is less than the first preset value, it indicates that the door panel 91 is not moved or rotated, that is, the indoor space is not in use or is not just used, and step S6 is continuously performed.

In step S7, the temperature sensing unit 4 performs temperature detection. When the temperature sensing unit 4 detects that the body temperature of the user's hand is higher than the room temperature of the indoor space, the temperature sensing signal is generated. Then, step S7 is continuously performed. When the temperature detected by the temperature sensing unit 4 is substantially equal to the room temperature of the indoor space, the temperature sensing signal is not generated, and step S8 is performed.

In step S8, the processing unit 1 generates the driving signal, so that the driving unit 6 drives the spraying mechanism 9 to eject the cleaning agent, and then performs step S9.

In step S9, the processing unit 1 decrements the stored number of available times by one, and then performs step S10.

In step S10, the processing unit 1 determines whether the available number of times is equal to zero, and when the available number of times is equal to zero, step S2 is performed. When the available number of times is not equal to zero, step S11 is performed.

In step S11, the processing unit 1 resets the timing to zero. For example, the processing unit 1 includes a timer (not shown) for calculating the time from the previous generation of the driving signal. Because the step S8, the processing unit 1 generates the driving signal, so that the spraying mechanism 9 ejects the cleaning agent, and the processing unit 1 resets the timer to the second preset value for timing to zero, and then performs the step. S12.

In step S12, the timer of the processing unit 1 counts down. When the timer passes the time corresponding to the second preset value, the value counted by the timer becomes zero, and then step S6 is performed.

Briefly, the flowchart exemplarily illustrates that the processing unit 1 performs ambient light source detection by step S4, and then performs motion detection of the door panel 91 by step S6, and is avoided by temperature detection of step S7. The user's hand is accidentally sprayed, and the spray mechanism 9 is driven to eject the detergent by the step S8. And after the cleaning agent is ejected, when the third predetermined value is re-timed, the process returns to step S6 to make a determination of the ambient light source detection again.

A second embodiment of the novel automatic cleaning device is substantially the same as the first embodiment, except that the cleaning agent is an air fragrance, and the spraying mechanism 9 does not have to be disposed on the door panel 91. And the automatic cleaning device does not include the temperature sensing unit 4.

In summary, the ambient light source sensing unit 3 detects whether the indoor space is in the working period, and the acceleration sensing unit 2 detects whether the indoor space has a user in use or just used, so that the The processing unit 1 ejects the cleaning agent at a time interval at least corresponding to the third predetermined value to perform cleaning efficiently. In addition, the temperature sensing unit 4 detects whether the user's hand is or is touching the door handle 92 to avoid accidental ejection, so that the object of the present invention can be achieved.
