Detailed Description

The utility model is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the utility model and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present utility model are shown in the drawings.

The embodiment of the utility model provides a non-contact type induction device which is applied to non-contact type switch equipment. The non-contact type switching device may be a non-contact type elevator key, a non-contact type wall switch, a non-contact type water outlet device, etc., but is not limited thereto. Fig. 1 is a schematic structural diagram of a non-contact induction device according to an embodiment of the present utility model, referring to fig. 1, a non-contact induction device 10 includes an anti-interference sensor assembly 1, an induction sensor assembly 2 and a controller 3, wherein the anti-interference sensor assembly 1 and the induction sensor assembly 2 are respectively electrically connected with the controller 3, and the controller 3 is electrically connected with a switch (not shown in the figure); the controller 3 comprises an interference signal receiving end 31 and an induction signal receiving end 32, the interference signal receiving end 31 is electrically connected with the anti-interference sensor assembly 1, and the induction signal receiving end 32 is electrically connected with the induction sensor assembly 2; the controller 3 controls the switch to keep the off state according to the interference signal received by the interference signal receiving end 31; the controller 3 controls the switch to be turned on according to the sensing signal received by the sensing signal receiving terminal 32.

Fig. 1 is a schematic diagram of a circuit connection structure of a non-contact induction device 10, which is not a physical structure diagram. As shown in fig. 1, in the embodiment of the present application, two sensor assemblies, that is, an anti-interference sensor assembly 1 and an induction sensor assembly 2, are disposed in a non-contact induction device, and the anti-interference sensor assembly 1 and the induction sensor assembly 2 are both infrared sensor assemblies. The anti-interference sensor assembly 1 is used for detecting external interference light, and the sensing sensor assembly 2 is used for detecting normal reflection light. When the user needs to control the non-contact switching device to be turned on, the user's hand may be close to the inductive sensor assembly 2.

The external interference light may refer to reflected light reflected by an interference object, such as light reflected by a surface of an object with relatively high reflectivity (e.g., a reflective vest), or infrared light emitted by other infrared devices, where the infrared signal emitted by the anti-interference sensor assembly 1 is reflected by the interference object. The normal reflected light refers to the reflected light collected by the sensor assembly 2 and reflected back by the hand or other parts of the user when the user makes an indication action in the detection area of the sensor assembly 2. That is, the anti-interference sensor assembly does not receive the normal reflected light, and is only used for detecting the interference signal, while the sensing sensor assembly 2 can receive both the interference light and the normal reflected light.

Further, the tamper sensor assembly 1 generates a tamper signal according to the detected tamper light, and the sensor assembly 2 generates a sensing signal according to the detected normal reflected light. The interference signal and the sensing signal may be analog signals, and the sensor assembly may convert the detected reflected light into corresponding electrical signals. In general, there is a difference between the external interference light and the normal reflected light, such as the intensity or wavelength of the external interference light and the normal reflected light, and there may be a certain difference between the electrical signals converted by the sensor assembly, that is, a certain difference between the interference signal and the sensing signal. For example, due to the strong reflectivity of the reflective vest, the intensity of the external disturbing light may be greater than that of the normal reflected light, and the waveforms of the disturbing signal and the sensing signal may have a certain difference.

With continued reference to fig. 1, the tamper sensor assembly 1 is electrically connected to the tamper signal receiving end 31 of the controller 3, and the sensor assembly 2 is electrically connected to the sensor signal receiving end 32 of the controller 3. The interference signal generated by the anti-interference sensor assembly 1 or the induction signal generated by the induction sensor assembly 2 is sent to the controller 3, and the controller 3 can judge whether the interference light exists according to the signal fed back by the anti-interference sensor assembly 1 and judge whether the user triggering action exists according to the signal fed back by the induction sensor assembly 2. The controller 3 is electrically connected with a switch in the non-contact type switch device, and when the controller 3 receives the interference signal but does not receive the induction signal, the fact that no user triggering action exists at present is indicated, and the light rays triggering the induction sensor assembly 2 are external interference light rays; the control signal output terminal (not shown in the figure) of the controller 3 can output a closing signal to control the switch to maintain the closed state. When the controller 3 does not receive the interference signal and receives the sensing signal, the fact that the user trigger action exists currently is indicated, and the light which triggers the sensing sensor assembly 2 is normal reflection light; the control signal output end of the controller 3 can output an opening signal to control the switch to be opened. It is also understood that the controller 3 controls the switch to be turned on only when the sensing signal is received.

The advantage of providing the tamper sensor assembly 1 is that the controller 3 can directly determine whether there is any disturbing light according to the signal fed back by the tamper sensor assembly 1. The problem that the switch is triggered by mistake because the induction sensor component 2 is only arranged in the related art and the induction sensor component 2 generates an electric signal similar to or the same as the interference signal when detecting the interference light similar to the normal reflection light is avoided.

Note that, the sensing signal receiving end 32 of the controller 3 is a port for receiving the electrical signal generated and emitted by the sensing sensor assembly 2, and is not represented by receiving only the sensing signal. When the sensor assembly 2 receives the disturbing light, the sensor assembly 2 does not generate a sensing signal, but generates a corresponding further electrical signal (which may be the same further disturbing signal as the disturbing signal), which is also received by the controller 3 via the sensing signal receiving terminal 32.

In this setting mode, when no interference object exists outside, the anti-interference sensor component 1 cannot receive interference light, the controller 3 cannot receive interference signals, at this time, the non-contact sensing device is in a non-interference working mode, and the controller 3 controls the on state of the switch according to the sensing signals transmitted by the sensing sensor component 2. When there is the user to trigger the action, the staff can be close to the inductive sensor assembly 2 and keep away from inductive sensor assembly 2 again, inductive sensor assembly 2 receives the reflection light that is from weak to strong and weakens again, the reflection light that satisfies weak-strong-weak change law that inductive sensor assembly 2 received can be the normal reflection light under the noninterference mode, inductive sensor assembly 2 generates corresponding inductive signal this moment, controller 3 control switch opens, when there is not the user to trigger the action, inductive sensor assembly 2 does not generate inductive signal, controller 3 control switch keeps closing, realize non-contact induction device's normal response under the noninterference mode of operation.

When an interference object exists outside, the anti-interference sensor assembly 1 receives interference light, the controller 3 receives an interference signal transmitted by the anti-interference sensor assembly 1, the non-contact sensing device is in an interference working mode, and the controller 3 controls the on state of the switch according to the interference signal and the sensing signal. Illustratively, in the absence of a user-triggered action, the inductive sensor assembly 2 also receives interfering light returned via an interfering object. Since the sensing sensor assembly 2 does not receive the normal reflected light, the sensing sensor assembly 2 does not generate a sensing signal, but generates an interference signal corresponding to the interference light. The sensor assembly 2 transmits an interference signal to the controller 3. The controller 3 does not receive the induction signal, but simultaneously receives the interference signal transmitted by the anti-interference sensor assembly 1 and the interference signal received by the induction sensor, and the controller 3 controls the switch to keep the closed state, so that false triggering of the non-contact induction device is avoided. When a user triggers the action, a human hand approaches the induction sensor assembly 2 and then moves away from the induction sensor assembly 2, and the human hand can block the interference light entering the induction sensor assembly 2, so that the light received by the induction sensor assembly 2 is weakened by strong and then strengthened, the reflected light which meets the strong-weak-strong change rule and is received by the induction sensor assembly 2 can be normal reflected light, and at the moment, the induction sensor assembly 2 generates a corresponding induction signal; the controller 3 receives the induction signal and triggers the switch to be turned on. Thus, normal induction of the non-contact induction device in the interference working mode can be realized.

Fig. 2 is a waveform diagram of an electrical signal corresponding to an interference light provided by an embodiment of the present utility model, fig. 3 is a waveform diagram of an electrical signal corresponding to a normal reflected light provided by an embodiment of the present utility model, and fig. 4 is a waveform diagram of an electrical signal corresponding to a sensor component provided by an embodiment of the present utility model when the sensor component does not receive a reflected light signal. FIG. 2 corresponds to the reflected light signal detected by the sensor assembly when the reflective vest is 30cm from the sensor assembly, the reflected light signal having a spike with a peak intensity of approximately 1.37V. When the anti-interference sensor assembly and the induction sensor assembly generate the electric signals similar to those shown in fig. 2 at the same time, the external interference light exists, and the non-contact induction device enters an interference working mode. Fig. 3 corresponds to a reflected light signal detected by the sensor assembly when a human hand is 5cm from the sensor assembly, the reflected light signal having a peak with a peak intensity of approximately 0.9V. Fig. 4 corresponds to the reflected light signal detected by the sensor assembly without interfering light nor human hand reflected light, the reflected light signal having no spike, and the overall maximum intensity being about 0.08 v. When the anti-interference sensor assembly and the induction sensor assembly generate the electric signals similar to those shown in fig. 4 at the same time, it is indicated that no interference light exists in the outside, no indication action is made by a user, and the non-contact induction device enters a non-interference working mode. In the non-interference operation mode, if the sensing sensor assembly generates an electrical signal similar to that shown in fig. 3, the user is indicated to perform the indication action, and the controller controls the switch to be turned on. It should be noted that the waveforms shown in fig. 2 to 4 are only a few exemplary waveforms, which are only a few possible waveforms obtained during the experimental process, and are not representative of the waveforms of the electrical signals generated by the sensor assembly in practical applications.

The control switch may be turned on by controlling a switching circuit to be turned off, and the control switch may be turned off by controlling a switching circuit to be turned off, and the switch may refer to a switching element such as a solenoid valve in the non-contact switching device, but is not limited thereto. In addition, the specific structures of the tamper sensor assembly 1 and the induction sensor assembly 2 may be obtained by those skilled in the art using any prior art, and the present application is not repeated herein nor limited thereto.

It will be appreciated that when the non-contact type sensing device 10 is applied to a non-contact type switchgear, both the tamper sensor assembly 1 and the sensing sensor assembly 2 may be disposed on the outer surface of the switchgear, such that the tamper sensor assembly 1 and the sensing sensor assembly 2 respectively emit infrared light (or infrared signals) outwards.

In the application, the non-contact induction device comprises an anti-interference sensor assembly, an induction sensor assembly and a controller, wherein the anti-interference sensor assembly and the induction sensor assembly are respectively and electrically connected with the controller, and the controller is electrically connected with the switch; the controller comprises an interference signal receiving end and an induction signal receiving end, wherein the interference signal receiving end is electrically connected with the anti-interference sensor assembly, and the induction signal receiving end is electrically connected with the induction sensor assembly; the controller controls the switch to keep a closed state according to the interference signal received by the interference signal receiving end; the controller controls the switch to be turned on according to the induction signal received by the induction signal receiving end. Through the scheme, the anti-interference performance of the non-contact type induction device can be improved, and the non-contact type induction device can work normally in an interference mode and a non-interference mode.

Wherein, for different types of non-contact switchgear, the number of the anti-interference sensor components and the sensing sensor components arranged in the non-contact sensing device can be different. For example, a contactless sensor device may be provided that includes at least one tamper sensor assembly and at least one sensor assembly, and the number of tamper sensor assemblies may be the same or different from the number of sensor assemblies.

Optionally, fig. 5 is a schematic partial structure diagram of a non-contact sensing device according to an embodiment of the present utility model, and referring to fig. 5, in a possible embodiment, an anti-interference sensor set 1 includes a first infrared transmitting unit 101 and a first infrared receiving unit 102; the first infrared ray transmitting unit 101 transmits a first infrared signal outwardly; the first infrared receiving unit 102 is electrically connected with an interference signal receiving end (not shown in the figure), and the first infrared receiving unit 102 receives a first reflected signal that the first infrared signal is reflected by an object and generates an interference signal according to the first reflected signal; the induction sensor assembly 2 includes a second infrared transmitting unit 201 and a second infrared receiving unit 202; the second infrared ray transmitting unit 201 is configured to transmit a second infrared signal outwards; the second infrared receiving unit 202 is electrically connected to a sensing signal receiving end (not shown in the figure), and the second infrared receiving unit 202 receives a second reflected signal of the second infrared signal reflected by the object and generates a sensing signal according to the second reflected signal.

In this embodiment, the anti-interference sensor assembly 1 may be formed by a first infrared transmitting unit 101 and a first infrared receiving unit 102, where the first infrared transmitting unit 101 transmits a first infrared signal outwards, the first infrared signal is reflected by an interfering object to form a first reflected signal, the first infrared receiving unit 102 receives the first reflected signal, and the first reflected signal is the above-mentioned interference light, so as to generate an interference signal according to the first reflected signal. The first infrared receiving unit 102 transmits the interference signal to the interference signal receiving end of the controller.

Correspondingly, the induction sensor assembly 2 may be composed of a second infrared transmitting unit 201 and a second infrared receiving unit 202, where the second infrared transmitting unit 201 transmits a second infrared signal outwards, the second infrared signal is reflected by a human hand to form a second reflected signal, and the second infrared receiving unit 202 receives the second reflected signal, and the second reflected signal is the normal reflected light mentioned above, so as to generate an induction signal according to the second reflected signal. The second infrared receiving unit 202 transmits the sensing signal to the sensing signal receiving end 32 of the controller 3. When the second infrared signal is reflected by the interfering object, the second infrared receiving unit 202 receives the interfering light, rather than the second reflected signal.

The specific setting modes of the infrared transmitting unit and the infrared receiving unit can be set by a person skilled in the art according to actual situations, and the application is not repeated and limited.

Optionally, in the embodiment of the present application, in order to avoid that the tamper sensor assembly 1 receives a normal reflection signal reflected by a user, the relative position between the tamper sensor assembly 1 and the sensor assembly 2, and/or the internal parameters of the tamper sensor assembly 1 and the sensor assembly 2, etc. may be designed.

By way of example, in a possible embodiment, the tamper sensor assembly 1 and the inductive sensor assembly 2 may be arranged at a distance from the surface of the device housing. So that the first infrared emission signal emitted by the tamper sensor assembly 1 does not pass through the location of the user when the user approaches the sensor assembly 2.

For example, in other possible embodiments, the transmission power of the first infrared signal transmitted by the first infrared transmitting unit 101 may be set to be smaller than the transmission power of the first infrared signal transmitted by the second infrared transmitting unit 201.

It will be appreciated by those skilled in the art that the emitted power of the infrared signal will affect the detection of the infrared signal. For the same object at the same distance, the larger the transmitting power of the infrared signal is, the stronger the intensity of the reflected light received by the infrared receiving unit is; whereas the intensity of the reflected signal received by the infrared receiving unit is relatively weak or the reflected signal is not received.

In the present embodiment, the transmission power of the infrared signal (first infrared signal) emitted by the first infrared emission unit 101 in the tamper sensor assembly 1 may be set to be weaker than the transmission power of the infrared signal (second infrared signal) emitted by the second infrared emission unit 201 in the induction sensor assembly 2. In this way, after the user makes the indication action, the intensity of the second reflected signal obtained by reflecting the second infrared signal by the human hand is stronger, and the second infrared receiving unit 202 can generate the induction signal according to the second reflected signal; the intensity of the reflected signal obtained by the first infrared signal through the transmission of the human hand is weak and can be basically ignored, and the first infrared receiving unit 102 does not generate an interference signal. In addition, since the reflection effect of the interfering object on the infrared ray is stronger than the reflection effect of the human hand, the first infrared ray receiving unit 102 can normally detect the interfering light ray (i.e., the first reflection signal) even if the transmission power of the first infrared signal is small.

In this way, the anti-interference sensor assembly 1 can be prevented from receiving normal reflection signals, and the accuracy of generating interference signals by the anti-interference sensor assembly 1 is ensured.

Optionally, in this embodiment of the present application, the sensing distance of the tamper sensor assembly 1 may be further set to be smaller than the sensing distance of the sensing sensor assembly 2.

The sensing distance is understood to mean the maximum distance of the reflected light rays reflected by the same object that can be received by the sensor assembly, i.e. the maximum distance of the reflected light rays reflected by the same object that can be received by the infrared receiving unit. The sensing distance of the tamper sensor assembly 1 is set to be smaller than the sensing distance of the sensing sensor assembly 2. Thus, when the hand is located within the sensing distance of the sensing sensor assembly 2, the sensing sensor assembly 2 can receive the reflected signal, but the anti-interference sensor assembly 1 cannot receive the reflected signal, so that the anti-interference sensor assembly 1 is further prevented from receiving the normal reflected signal.

The specific values of the respective sensing distances of the anti-interference sensor assembly 1 and the sensing sensor assembly 2 are not limited, and may be set by those skilled in the art according to actual requirements.

By way of example, in a possible embodiment, the sensing distance of the tamper sensor assembly 1 may be set to be less than or equal to 1cm, the sensing distance of the sensing sensor assembly 2 to be greater than or equal to 2cm, and less than or equal to 10cm.

In this arrangement, when the distance between the hand and the sensor assembly 2 is 2-10 cm, the sensor assembly 2 can receive the reflected light. Because the sensing distance of the anti-interference sensor component 1 is less than or equal to 1cm, when a user indicates the action within the sensing distance of the sensing sensor component 2, the anti-interference sensor component 1 cannot receive the reflected light of the human hand.

Wherein, the sensing distance of the sensor assembly can be adjusted by adjusting the infrared signal transmitting power of the infrared transmitting unit in the sensor assembly, but is not limited thereto. As described in the above embodiment, the transmission power of the first infrared signal transmitted by the first infrared transmitting unit 101 in the tamper sensor assembly may be set to be small, and the transmission power of the first infrared signal transmitted by the second infrared transmitting unit 201 in the induction sensor assembly may be set to be large, but is not limited thereto. The sensing distance of the sensor assembly can be adjusted in any known manner according to actual requirements by a person skilled in the art.

Based on the same conception, the embodiment of the utility model also provides non-contact type water outlet equipment, which comprises the non-contact type sensing device provided by any embodiment of the utility model.

Specifically, the non-contact type switch device may be a non-contact type water outlet device, and when the non-contact type switch device is a non-contact type water outlet device, the switch in the non-contact type switch device may be an electromagnetic valve in the water outlet channel. The non-contact water outlet device provided by the embodiment of the utility model can be a non-contact faucet, a non-contact water dispenser and the like, but is not limited to the non-contact faucet.

The non-contact water outlet device provided by the embodiment of the utility model comprises all technical features and corresponding beneficial effects of the non-contact sensing device provided by any embodiment of the utility model, and is not repeated here.

Alternatively, fig. 6 is a schematic diagram of a partial structure of a non-contact water outlet device according to an embodiment of the present utility model, taking the non-contact water outlet device 100 as an example of a non-contact water dispenser, and fig. 6 schematically illustrates a partial structure of the non-contact water dispenser. Referring to fig. 6, the non-contact type water outlet apparatus 100 may include a plurality of water outlet channels (not shown) and a plurality of channel switches (not shown) disposed on the water outlet channels in a one-to-one correspondence; the non-contact sensing device comprises at least one anti-interference sensor assembly 1, a plurality of sensing sensor assemblies 2 and a controller (not shown in the figure), wherein the controller is electrically connected with the channel switch; the controller comprises at least one interference signal receiving end and a plurality of induction signal receiving ends; the at least one interference signal receiving end is electrically connected with the at least one anti-interference sensor assembly 1 in a one-to-one correspondence manner, and the plurality of induction signal receiving ends are electrically connected with the plurality of induction sensor assemblies 2 in a one-to-one correspondence manner; the controller controls at least one channel switch to keep a closed state according to the interference signal received by the interference signal receiving end; the controller correspondingly controls one channel switch to be opened according to the induction signals received by the induction signal receiving ends.

Specifically, the water outlet channel is the water outlet of the non-contact water dispenser, and the channel switch is the valve used for controlling whether the water flow flows down on the water outlet channel. For example, the water outlet passage may include a hot water outlet passage and a cold water outlet passage, but is not limited thereto. The embodiment of the utility model is not limited to the specific arrangement structure of the water outlet channel and the channel switch.

Further, referring to fig. 6, when the non-contact type sensing device is applied to the non-contact type water outlet apparatus 100 of the present embodiment, at least one tamper sensor assembly 1, a plurality of sensing sensor assemblies 2, and a controller (not shown) may be provided in the non-contact type water outlet apparatus 100. The number of the sensing sensor assemblies 2 is the same as the number of the water outlet channels, and the number of the tamper proof sensor assemblies 1 may be less than or equal to the number of the water outlet channels.

Accordingly, the at least one anti-interference sensor assembly 1 is connected with at least one interference signal receiving end (not shown in the figure) of the controller, and the plurality of induction sensor assemblies 2 are electrically connected with a plurality of induction signal receiving ends (not shown in the figure) of the controller in a one-to-one correspondence manner.

In this embodiment of the present application, an induction sensor assembly 2 may be configured for each channel switch (also may be understood as a water outlet channel), when a user wants to get water from which water outlet channel, the user may approach the hand to the induction sensor assembly 2 corresponding to the water outlet channel, the induction sensor assembly 2 generates an induction signal, and the induction signal is transmitted to the controller through an induction signal receiving end corresponding to the induction sensor assembly 2, and the controller controls the opening of the channel switch corresponding to the induction sensor assembly 2, so that water is discharged from the water outlet channel. Since the tamper sensor assembly 1 is used to detect the tamper light, which does not detect the indication action of the user, the number of tamper sensor assemblies 1 may be set smaller than the number of sensing sensor assemblies 2. That is, the same tamper sensor assembly 1 may be used to detect stray light at least one sensing sensor assembly 2.

For example, if only one tamper sensor assembly 1 is provided, and when the tamper sensor assembly 1 detects a tamper light, the controller receives the tamper signal, the non-contact sensing device may enter a tamper mode of operation. At this time, if any induction sensor component 2 does not receive an induction signal, the controller controls all the channel switches to be kept closed, and the non-contact water outlet device cannot discharge water, so that false triggering of the water outlet device is avoided. If a certain induction sensor component 2 receives an induction signal, the controller controls a channel switch corresponding to the induction sensor component 2 to be opened, and the water outlet channel is used for discharging water, so that normal induction under an interference mode is realized. The same anti-interference sensor assembly 1 is arranged to correspond to the plurality of induction sensor assemblies 2, so that the assembly process and the assembly difficulty of the non-contact water outlet equipment can be simplified.

Illustratively, if the number of tamper sensor assemblies 1 is the same as the number of sensor assemblies 2, each tamper sensor assembly 1 detects a tamper ray in the vicinity of the corresponding sensor assembly 2. In this way, it is ensured that the disturbing light in the vicinity of each sensor assembly 2 is detected by the corresponding tamper sensor assembly 1. Avoiding the situation that no disturbing light at a certain sensor assembly 2 can be detected.

Those skilled in the art will appreciate that different sensor assemblies 2 may be provided in different areas of the housing of the water outlet device. If the anti-interference sensor assembly 1 and the plurality of induction sensor assemblies 2 are arranged in the water outlet equipment, the anti-interference sensor assembly 1 can be arranged at the central position of the pattern formed by the plurality of induction sensor assemblies 2, that is, the distances between the anti-interference sensor assembly 1 and the different induction sensor assemblies 2 are the same, so that the anti-interference sensor assembly 1 can detect the interference light rays at the plurality of induction sensor assemblies 2. If a plurality of tamper sensor assemblies 1 and a plurality of induction sensor assemblies 2 are provided in the water outlet apparatus, each tamper sensor assembly 1 can be disposed in the vicinity of each induction sensor assembly 2 in a one-to-one correspondence manner, and thus, the tamper sensor assemblies 1 detect the disturbing light at the corresponding induction sensor assemblies 2.
