In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present utility model.

The utility model provides a photoelectric sensing component.

In an embodiment of the present utility model, as shown in fig. 1 to 4, the photo-sensing assembly includes a drive plate 10, a photo-sensor 20, and a shutter 24.

The drive board 10 includes a Microprocessor (MCU), capacitive, resistive electronic components, and a Printed Circuit Board (PCB) carrying and connecting these electronic components.

The photosensor 20 is provided to the drive board 10, and the photosensor 20 includes a transmitting unit 22 and a receiving unit 23. Wherein the transmitting unit 22 is used for transmitting the photoelectric signal outwards, and the receiving unit 23 is used for sensing the photoelectric signal transmitted by the transmitting unit 22. In short, when the photoelectric signal sent by the transmitting unit 22 is reflected by an external object and the reflected photoelectric signal is sensed by the receiving unit 23, the photoelectric sensor 20 is triggered, and then a trigger signal can be sent to the microprocessor on the driving board 10, and the microprocessor can automatically execute subsequent operations after receiving the trigger signal, so as to realize automatic control of the device.

Further, in the technical solution of the present application, the transmitting unit 22 and the receiving unit 23 are arranged on the driving board 10 side by side, the shielding member 24 is arranged between the transmitting unit 22 and the receiving unit 23, the shielding member 24 extends in a direction away from the driving board 10, the extending direction of the shielding member 24 is the same as the direction of the light emitting side of the transmitting unit 22, and one end of the shielding member 24 facing away from the driving board 10 is higher than the transmitting end of the transmitting unit 22.

Here, the light emitting side of the emitting unit 22 refers to the side of the emitting unit 22 emitting the photoelectric signal, and it is understood that the light sensing side of the receiving unit 23 refers to the side of the receiving unit 23 sensing the reflected photoelectric signal.

It should be noted that, the conventional automatic sensing device generally works under the condition that the sensing panel is tightly attached to the photoelectric sensor 20, when the device requires that the sensing panel is movable compared with the photoelectric sensor 20, in order to realize the movement of the sensing panel compared with the photoelectric sensor 20, the sensing panel and the photoelectric sensor 20 must be arranged at intervals, so as to prevent the sensing panel from being tightly attached to the photoelectric sensor 20, which results in friction with the photoelectric sensor 20 when the sensing panel moves, so that the abrasion of the sensing panel and the photoelectric sensor 20 is caused, and the service life and sensing accuracy of the photoelectric sensor 20 are affected. However, when we set the sensing panel and the photoelectric sensor 20 at intervals, when the photoelectric signal emitted by the emitting unit 22 passes through the sensing panel, the side of the sensing panel facing the photoelectric sensor 20 reflects relatively more photoelectric signals (when the sensing panel is attached to the photoelectric sensor 20, the sensing panel still reflects a very small amount of photoelectric signals), and these reflected photoelectric signals are sensed by the adjacent receiving units 23, so that the photoelectric sensor 20 is triggered by errors, and the detection accuracy of the photoelectric sensor 20 is affected.

In the technical scheme of the application, the shielding piece 24 can shield at least part or all of photoelectric signals reflected to the receiving unit 23 by the sensing panel, so that the photoelectric signals which can be sensed by the receiving unit 23 are reduced, and further the photoelectric sensor 20 can be prevented from being triggered by mistake. It will be appreciated that since the shutter 24 is disposed between the transmitting unit 22 and the receiving unit 23, the receiving unit 23 is still able to sense a portion of the photoelectric signal reflected by the external object, so that the photoelectric sensor 20 can operate normally.

In the photoelectric sensing assembly according to the technical scheme of the utility model, the shielding member 24 is arranged between the transmitting unit 22 and the receiving unit 23, and the shielding member 24 is higher than the transmitting end of the transmitting unit 22, so that at least part or all of photoelectric signals reflected to the receiving unit 23 by the sensing panel can be shielded by the shielding member 24, and the receiving unit 23 is prevented from being triggered by mistake, thereby being capable of reducing the probability of false touch of the photoelectric sensor 20 while ensuring that the sensing panel is arranged at intervals with the photoelectric sensor 20. Therefore, compared with the traditional automatic induction scheme with a movable induction panel, the photoelectric induction component of the technical scheme has the advantage of improving the working reliability of automatic induction equipment.

In some embodiments, the photoelectric sensor 20 further includes a light shielding shell 21, the light shielding shell 21 is hollow, the shielding member 24 is disposed in the light shielding shell 21, and two mounting cavities are separated in the light shielding shell 21, the two mounting cavities form windows on the surface of the light shielding shell 21, the transmitting unit 22 is disposed in one of the two mounting cavities, and the receiving unit 23 is disposed in the other of the two mounting cavities.

Specifically, by providing the hollow light shielding case 21 and dividing the light shielding case 21 into two mounting cavities by the shutter 24 and mounting the transmitting unit 22 and the receiving unit 23 in the mounting cavities, the transmitting unit 22 and the receiving unit 23 can be protected. Meanwhile, the photoelectric signal sent by the transmitting unit 22 can be blocked by the shielding piece 24, so that the photoelectric signal sent by the transmitting unit 22 is prevented from directly entering the receiving unit 23, and false triggering of the photoelectric sensor 20 is avoided. Of course, in other embodiments, the photosensor 20 may not be provided with the light shielding shell 21.

In some embodiments, one of the two mounting cavities includes a first cavity 211 and a light emitting channel 212 in communication with each other, the other includes a second cavity 213 and a light entering channel 214 in communication with each other, and the light emitting channel 212 and the light entering channel 214 form windows on the surface of the light shielding shell 21, respectively; wherein,,

the emitting unit 22 is disposed in the first cavity 211 and faces the light emitting channel 212, and the receiving unit 23 is disposed in the second cavity 213 and faces the light entering channel 214.

Specifically, the photoelectric signal emitted by the emission unit 22 needs to pass through the light emitting channel 212, when the photoelectric signal passes through the light emitting channel 212, the photoelectric signal is collected, the light collecting effect of the photoelectric sensor 20 is better, so that the photoelectric signal sensed by the receiving unit 23 is stronger, and when the reflected photoelectric signal enters the light entering channel 214, the photoelectric signal is collected in the light entering channel 214, so that the intensity of the photoelectric signal received by the receiving unit 23 is higher, that is, the sensitivity of the photoelectric sensor 20 is higher. Of course, in other embodiments, the mounting cavity may not have the light emitting channels 212 and the light entering channels 214.

In some embodiments, the maximum cross-sectional area of the light emitting channel 212 is less than the maximum cross-sectional area of the first cavity 211. Specifically, after the photoelectric signal emitted by the emission unit 22 enters the light-emitting channel 212, since the maximum cross-sectional area of the light-emitting channel 212 is smaller than that of the first cavity 211, the photoelectric signal is collected when the photoelectric signal passes through the light-emitting channel 212, so that the light-collecting effect of the photoelectric sensor 20 is better, the photoelectric signal sensed by the receiving unit 23 is more concentrated, and the sensitivity of the photoelectric sensor 20 is higher. Of course, in other embodiments, the maximum cross-sectional area of the light-emitting channel 212 may be greater than or equal to the maximum cross-sectional area of the first cavity 211.

In some embodiments, the maximum cross-sectional area of the light inlet channel 214 is less than the maximum cross-sectional area of the second cavity 213. Specifically, under the condition that the maximum cross-sectional area of the light inlet channel 214 is smaller than the maximum cross-sectional area of the second cavity 213, the light inlet channel 214 can shield part of the photoelectric signals, so that the photoelectric signals cannot enter the light inlet channel 214 and are sensed by the receiving unit 23, and the other part of the photoelectric signals entering the light inlet channel 214 are collected by the light inlet channel 214 and are further sensed by the receiving unit 23, that is, when the photoelectric sensor 20 keeps correct triggering precision, the photoelectric sensor 20 can be prevented from being triggered by mistake. Of course, in other embodiments, the maximum cross-sectional area of the light inlet channel 214 may be greater than or equal to the maximum cross-sectional area of the second cavity 213.

In some embodiments, the shield 24 is integrally formed with the shield 21. It can be appreciated that the integral molding process has high production efficiency and high structural strength, and is also beneficial to reducing the production cost. Of course, the design of the present application is not limited thereto, and in other embodiments, the shield 24 may be attached to the light shielding shell 21 by bonding, welding, clamping, fastening with fasteners, or the like.

In some embodiments, the photosensor 20 includes an infrared sensor. Specifically, the type of the infrared sensor may be ITR001 infrared reflective photosensor 2020, GP2AP002S00F infrared proximity sensor, LTH-1550-01 reflective photosensor 2020, etc. It will be appreciated that the present application employs an infrared sensor as the photoelectric sensor 20, and has advantages of high detection sensitivity, rapid response, and the like in the process of use. It should be noted that the design of the present application is not limited thereto, and in other embodiments, the photosensor 20 includes a laser sensor.

In some embodiments, the material of the light shielding shell 21 is at least one of plastic, rubber, and silicone. Specifically, the light shielding shell 21 made of one of plastic, rubber and silicone materials has elasticity, facilitating the installation of the transmitting unit 22 and the receiving unit 23 inside the light shielding shell 21.

Specifically, the transmission mechanism 51 includes a first gear 511 and a second gear 512, the first gear 511 is provided on the output shaft of the motor 52, the second gear 512 is provided on the cylinder head 40, and the first gear 511 is engaged with the second gear 512.

It can be appreciated that by adopting two gear meshing transmissions, the space between the cylinder cover 40 and the motor 52 is utilized to provide gears, so that the automatic ashtray is compact and simple in structure and high in stability through gear transmission. In addition, the modulus ratio of the first gear 511 and the second gear 512 can be adjusted, so that the rotation speed of the motor 52 can be reduced, and the cylinder cover 40 is more stable and smoother when driven to rotate by the motor 52. It will be appreciated that the cylinder head 40 is not directly mounted to the output shaft of the motor 52, so that the cylinder head 40 may be removed independently of the motor 52, facilitating later maintenance and earlier assembly. It should be noted that, the design of the present application is not limited thereto, and in other embodiments, the transmission mechanism 51 may be configured as a pulley transmission mechanism 51, where the pulley transmission mechanism 51 includes a first pulley and a second pulley, the first pulley is disposed on the output shaft of the motor 52, the second pulley is disposed on the cylinder cover 40, and the first pulley and the second pulley are connected by a belt.
