Description

Non-contact control switch

The new model relates to a control switch, in particular to a non-contact control switch.

After the user presses the switch with a little force, the corresponding light on the elevator panel is controlled to light up, so that the user can confirm that the switch is indeed pressed and can be operated. Elevator action.

However, once the user's finger contains bacteria or viruses, the bacteria or viruses on the finger will be attached to the surface of the switch when the switch is touched, which makes it easy for the next user to touch the switch directly. or virus infection. Therefore, there is still room for improvement in the current touch switch.

Therefore, the purpose of the present invention is to provide a non-contact control switch capable of at least overcoming the shortcomings of the prior art.

Therefore, the novel non-contact control switch is suitable for an electrical appliance and a user. The non-contact control switch includes a housing, at least one switch module, and a control module.

The control module is suitable for signal connection to the electrical appliance, and signal connection to the first proximity sensing unit and the second proximity sensing unit of the at least one switch module. The control module generates a control signal capable of controlling the action of the electrical appliance when simultaneously receiving the first sensing signal and the second sensing signal.

The effect of the present invention lies in: using the design of the first proximity sensing unit and the second proximity sensing unit, the user's finger only needs to approach the switch without touching the switch, and the switch can sense the user and correspond to the Control the operation of electrical appliances to prevent different users from directly touching the switch, which increases the chance of spreading bacteria and viruses through the switch, and reduces the risk of indirect contact infection. On the other hand, by using the arrangement of two sets of proximity sensing units, it can further avoid the situation that the switch misjudges and causes the electrical appliance to act erroneously.

Sensing and controlling the electric appliance 4 to act. In this embodiment, the electrical appliance 4 is, for example, but not limited to, an elevator, and the electrical appliance 4 can also be other electrical appliances 4 such as an automatic door, depending on the needs of the user.

The non-contact control switch includes a housing 1 , a plurality of switch modules 2 mounted on the housing 1 , and a control module 3 disposed on the housing 1 and signally connected to the switch modules 2 .

The housing base 1 is generally square, and includes a mounting plate 11 and a plurality of main housings 12 . Each main casing 12 has a light-transmitting portion 121 for light to pass through, and an accommodating space 122 .

Each switch module 2 includes a first proximity sensing unit 21 , a second proximity sensing unit 22 , and a light emitting unit 23 installed in the accommodating space 122 of the respective main casing 12 . Since the switch modules 2 have the same structure, only one of the switch modules 2 is shown in FIG. 3 .

The position of the first proximity sensing unit 21 corresponds to the transparent portion 121 , and includes a transmitter 211 capable of emitting an optical pulse signal passing through the transparent portion 121 to the outside, and a transmitter 211 capable of receiving reflections from the outside and passing through The light-transmitting portion 121 is a light-reflecting signal receiver 212 . The receiver 212 is used for inducing a first sensing signal when receiving the light reflection signal. In this embodiment, the first proximity sensing unit 21 is an infrared light interrupter, and in other variations of this embodiment, the first proximity sensing unit 21 can also be used for transmitting and receiving Optical sensors for light in wavelength ranges other than infrared.

The second proximity sensing unit 22 and the corresponding light-transmitting portion 121 of the main casing 12 are disposed on the rear side of the first proximity sensing unit 21 at intervals, so that the first proximity sensing unit 21 is disposed on the first proximity sensing unit 21 . Between the two proximity sensing units 22 and the transparent portion 121 . The second proximity sensing unit 22 can sense and generate a second sensing signal when the finger 91 of the user 9 is approached. In this embodiment, the second proximity sensing unit 22 is a proximity capacitive sensor.

The light-emitting unit 23 can be controlled to emit visible light, and the light can pass through the light-transmitting portion 121 to the outside, and the user can see the area of the light-transmitting portion 121 glowing. In this embodiment, the light-emitting unit 23 is an LED lamp.

The control module 3 is mounted on the mounting board 11 , and can be connected to the electrical appliance 4 with a signal, and the signal is connected to the first proximity sensing unit 21 , the second proximity sensing unit 22 of the switch module 2 , and The light-emitting unit 23 . The control module 3 generates a control signal when simultaneously receiving the first sensing signal and the second sensing signal of one of the switch modules 2 . The control signal controls the light-emitting unit 23 to emit light, and controls the electrical appliance 4 to act. In this embodiment, the control module 3 is a processor and corresponds to the control signals of different switch modules 2, which can respectively control the elevator to move to the corresponding floor, control the elevator door to open, and/or control the elevator door. The elevator doors are closed. Since the control module 3 controls the elevator operation is a known technology in the technical field, and can adjust the elevator moving speed and the time the elevator door is kept in the open state and other details according to the needs, so the operation mode and the operation mode of the electric appliance 4 will not be repeated here. manner.

Referring to FIG. 2 to FIG. 4 , when in use, the transmitter 211 first generates a light pulse signal and emits it through the light-transmitting portion 121 , and the finger 91 of the user 9 is close to and does not contact the transparent portion of one of the main casings 12 . When the light part 121 is used, the light pulse signal of the corresponding transmitter 211 is reflected by the finger to become the light reflection signal, and after the receiver 21 receives the light reflection signal, the first sensing signal is generated; and the second sensing signal is generated. The proximity sensing unit 22 changes the electric field due to the proximity of the finger 91 of the user 9 , thereby generating the second sensing signal. After that, when the first sensing signal and the second sensing signal are simultaneously transmitted to the control module 3, the control module 3 receives and generates the control signal synchronously, and then controls the light-emitting unit 23 to emit light, and controls the control module 3 to emit light. Elevator action. If the first sensing signal and the second sensing signal are not received at the same time, the elevator does not move. It should be noted that "simultaneously" here refers to the same time, and ignores the slight time difference generated during the generation and transmission of the first sensing signal and the second sensing signal.

Therefore, the user does not need to touch the non-contact control switch, that is, the switch module 2 can sense the finger 91 of the user 9, so as to avoid the spread of bacteria and viruses by multiple people directly touching the touch switch. Condition. In addition, the arrangement of the first and second proximity sensing units 21 and 22 of the non-contact control switch can also enhance the sensing accuracy of the switch module 2 and avoid the occurrence of one of the first and second proximity sensing units 21 . . 22 When the judgment is wrong, the electrical appliance 4 is activated by the control signal generated by the misjudgment and misoperation.

Referring to FIG. 5 , it is a second embodiment of the novel non-contact control switch. The second embodiment is similar to the first embodiment, and the difference lies in that: the second proximity sensing unit 22 and the first proximity sensing unit 21 of each switch module 2 are disposed in the corresponding the inner side of the main casing 12. With this design, the variation of the electric field between the second proximity sensing unit 22 and the finger 91 of the user 9 is not affected by the first proximity sensing unit 21 , thereby further improving the sensing accuracy.

Referring to FIG. 6 , it is a third embodiment of the novel non-contact control switch. The third embodiment is similar to the first embodiment, and the difference lies in that: the installation positions of the first proximity sensing unit 21 and the second proximity sensing unit 22 of each switch module 2 are reversed, and the first proximity sensing unit 22 One electrode of the two proximity sensing units 22 is made of a transparent conductive film, so that the second proximity sensing units 22 are transparent and light-transmitting.
