Description

Technical Field

[0001] The invention relates to self-service equipment, in particular to a curtain mechanism and self-service equipment thereof. Background Art

[0002] Since self-service equipment is easy to use and can be operated 24 hours a day, it can greatly relieve the work pressure of window staff. However, the large number of self-service equipment users and the close contact with many people make it difficult to avoid cross infection, so there is a great potential risk. Especially when an infectious disease breaks out, this risk increases exponentially, so it is necessary to sterilize the self-service equipment. However, the current self-service equipment has no disinfection design and can only be sterilized by manual periodic scrubbing with disinfectants. This waterproofing not only greatly increases the labor cost, but also cannot effectively avoid cross infection.

[0003] Although the applicant proposed a solution to the above problem in the Chinese invention patent application entitled "An Ultraviolet Sterilization Module and Self-service Equipment Thereof" filed on the same day as the present case, namely, sterilization by ultraviolet light irradiation, in actual application, it is impossible to determine who is infected and therefore, for the sake of safety, sterilization is generally performed immediately after one use. Therefore, the efficiency is extremely low and cannot meet the needs of large usage. In addition, the ultraviolet light directed to the touch screen is relatively concentrated, and the edge of the touch screen cannot be fully irradiated. Therefore, the protective effect is only greatly improved, but it has not yet reached medical-level protection.

[0004] The most important symptom of a human body after a virus or bacteria infection is fever, so the accuracy of using the measured body temperature as evidence to determine whether the infected person has developed symptoms is relatively high. Therefore, the applicant believes that by detecting the body temperature to determine whether the person is a high-risk infected person or an infected person, a high-risk infected person or an infected person can be fully sterilized after use to obtain a higher level of protection, even reaching the medical protection level; and for users who do not have a fever, ordinary disinfection after use can greatly improve the efficiency of the self-service device, thereby meeting both the needs of large-volume use and the needs of preventing cross-infection.

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0038] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0039] See also Figure 1 The self-service device of this embodiment includes a self-service machine 100, an electrical shell 110 is installed on the self-service machine 100, and an LED screen 130 is installed on the top of the electrical shell 110. The LED screen 130 is used to display information. In this embodiment, the LED screen is used to display advertisements and prompt information, such as the status of the self-service machine and whether it can be used.

[0040] A shield 120 is installed on the side of the electrical shell 110, and an operation slot 111 is provided on the electrical shell 110. A touch screen 152 is installed in the operation slot 111. The touch screen 152 is used to display information and input information by touch. An operation table 140 is also installed in the operation slot 111. The operation table 140 is provided with a first card insertion port 141, a second card insertion port 142, and an IC card reader 151. The first card insertion port 141 and the second card insertion port 142 are respectively connected to the inlets of two chip card readers, so that the chip card can be inserted into the card reader for card reading, such as an ID card reader for reading ID card information, a radio frequency card reader for reading bank card information, etc. The IC card reader is used for contactless reading of IC cards. These are all existing technologies. This embodiment is a modification performed on an existing ATM self-service machine, so this part of the technology can be directly implemented using existing equipment.

[0041] The first ultraviolet lamp board 161, the second ultraviolet lamp board 162, and the infrared temperature measurement module 200 are respectively installed on the top of the inner side of the operation slot 111. The first ultraviolet lamp board 161 and the second ultraviolet lamp board 162 are respectively installed with ultraviolet lamp beads. When the ultraviolet lamp beads are powered on, they emit ultraviolet light to irradiate the touch screen and the inner side of the operation slot 111.

[0042] The infrared temperature measurement module 200 detects the forehead temperature of the user by infrared temperature measurement. The infrared temperature measurement module 200 includes an infrared thermometer 210. The infrared thermometer 210 is used to detect the forehead temperature of the user by infrared temperature measurement. The existing forehead thermometer can be directly used. The outer shell of the infrared thermometer 210 is provided with a hinge groove 211. In this embodiment, the outer shell of the existing forehead thermometer is enlarged, and then the hinge groove 211 is provided on the enlarged part, so it does not affect its internal layout and the realization of its function.

[0043] One end of the plug rod 220 is installed in the hinge groove 211 and a hinge tube 230 is fixed on the end of the plug rod 220. The hinge tube 230 is hollow inside and its two ends are respectively assembled with the outer shell of the infrared thermometer 210 for circumferential rotation. After one end of the hinge tube 230 passes through the outer shell of the infrared thermometer 210, it is assembled and fixed with the first friction wheel 231. The end surface of the first friction wheel 231 is tightly attached to the end surface of the second friction wheel 242, so that the first friction wheel 231 and the second friction wheel 242 cannot rotate relative to the circumference or require a large torque to rotate relative to the circumference through friction. In this embodiment, the contact surfaces of the first friction wheel 231 and the second friction wheel 242 are respectively provided with rough surfaces, so as to increase the friction between the first friction wheel 231 and the second friction wheel 242.

[0044] The second friction wheel 242 is fixed to one end of the adjusting rod 240, and the other end of the adjusting rod 240 passes through the cavity opening inside the hinge cylinder 230 and is assembled and fixed to the pressing ring 241. The adjusting rod 240 is sleeved with an adjusting compression spring 250 on the part between the pressing ring 241 and the outer shell of the infrared thermometer 210. The adjusting compression spring 250 is used to apply a thrust to the pressing ring 241 away from the second friction wheel 242, thereby increasing the pressure between the first friction wheel 231 and the second friction wheel 242, thereby increasing the friction between the first friction wheel 231 and the second friction wheel 242. Of course, the end face of the first friction wheel 231 away from the second friction wheel 242 is also in close contact with the outer shell of the infrared thermometer 210, and the outer shell of the infrared thermometer 210 and the first friction wheel 231 are arranged on a rough surface on their contact surfaces. Thus, when in use, the second friction wheel 242 drives the adjusting rod 240 to move slightly axially, so that the first friction wheel 231 is in close contact with the outer shell of the infrared thermometer 210 and obtains a larger friction force, thereby relatively locking the angle between the plug-in rod 220 and the infrared thermometer 210 in the circumferential direction.

[0045] Of course, the adjusting rod 240 and the hinge cylinder 230 can also be assembled so that they cannot rotate in a circular direction but can move in an axial direction. Figure 8 In the state, the thrust applied by the adjusting compression spring to the pressing ring 241 is used to lock the adjusting rod 240 in the circumference, thereby achieving the locking of the circumference of the articulated cylinder.

[0046] The plug-in rod 220 is provided with an annular groove 221 and the plug-in rod is inserted into the plug-in hole 112. The plug-in hole 112 is provided on the electrical shell 110. The electrical shell 110 is also provided with a block slide groove 113 and a motor groove 114. The annular groove 211 is engaged with one end of the sliding block 260 to relatively fix the plug-in rod 220 in the axial direction, thereby realizing the assembly of the infrared temperature measurement module 200 and the self-service machine.

[0047] The sliding block 260 can slide in the block slot 113, and the block slot 113 is assembled and fixed with one end of the plug-in spring 270 away from one end of the plug-in rod 220, and the other end of the plug-in spring 270 is sleeved on one end of the plug-in output shaft 721, and a plug pin 280 is installed on this end of the plug-in output shaft 721, and the plug pin 280 is installed in the spiral gap of the plug-in spring 270; the other end of the plug-in output shaft 721 passes through the block slot 113 and enters the motor slot 114 and is installed in the plug-in motor 720, and the plug-in motor 720 can drive the plug-in output shaft 721 to rotate forward or reverse in the circumferential direction. The plug-in output shaft 721 is fitted with a second bevel gear 452, which meshes with the first bevel gear 451 for transmission. The first bevel gear 451 is fitted and fixed on one end of the lock core shaft 550, and the other end of the lock core shaft 550 is fixed on the lock core 440. The lock core 440 can be assembled with the electrical housing 110 for relative circular rotation.

[0048] When the infrared temperature measurement module 200 needs to be disassembled, the plug-in motor is started to drive the plug-in output shaft 721 to rotate in a circle, so that the plug-in pin 280 continuously rotates in the spiral gap of the adjustment spring to pull and compress the adjustment spring toward the plug-in motor until the sliding block 260 is out of the annular groove 221. Once the plug-in motor is damaged or cannot be started, it can be unlocked by inserting the key into the lock core 440 and then driving the lock core 440 to rotate in a circle, thereby driving the plug-in output shaft to rotate in a circle. When the infrared temperature measurement module 200 needs to be installed, the plug-in rod is fully inserted into the plug-in hole, and then the plug-in motor is reversed to reset the adjustment spring and re-install the sliding block 260 into the annular groove.

[0049] When the angle between the infrared thermometer 210 and the plug-in rod needs to be adjusted, the adjusting rod 240 can be pressed by the pressing ring to separate the first friction wheel 231 and the second friction wheel 242. At this time, the infrared thermometer 210 and the plug-in rod can be rotated to adjust the angle. After the adjustment is completed, the pressing ring 241 is released to restore the first friction wheel 231 and the second friction wheel 242 to be pressed tightly.

[0050] Since the first ultraviolet lamp board 161 and the second ultraviolet lamp board 162 are both arranged above the operation slot 111, the part below the operation slot may not be irradiated or the irradiated ultraviolet light is very weak, which greatly reduces its sterilization effect. Moreover, when the first ultraviolet lamp board 161 and the second ultraviolet lamp board 162 are started at the same time, the ultraviolet light is strong, which will affect the surrounding people. For this reason, the applicant has designed a curtain mechanism 600, and the curtain 310 of the curtain mechanism 600 blocks the ultraviolet light, thereby preventing the ultraviolet light from escaping and affecting the surrounding people.

[0051] The blind mechanism 600 includes a blind 310, the two ends of which are fixed on the third shaft 530 and the first belt 410 respectively. The blind 310 can be wound and rolled on the third shaft 530. The other end of the third shaft 530 passes through the electrical shell 110 and enters the protective cover 120 and is assembled and fixed with one end of the steel belt of the spring spring 430. The other end of the steel belt of the spring spring 430 is fixed on its shell and its shell is fixed on the electrical shell 110. When the blind 310 is rolled up on the third shaft 530 to reach the maximum rolled state, the spring spring 430 is in a non-maximum rolled state. When the blind 310 is unwound from the third shaft 530, the spring spring (steel belt) is gradually rolled up. The structure of the spring spring can refer to the existing retractable tape measure, and the ruler (the part with scale) of the tape measure can be regarded as a steel belt.

[0052] The first belt is respectively mounted on the two first pulleys 411, and the two first pulleys 411 are respectively mounted on the second shaft 520 and the first shaft 510, and the second shaft 520 and the first shaft 510 are respectively assembled with the electrical housing 110 so as to be rotatable in a circular manner;

[0053] One end of the second shaft body 520 passes through the electrical shell 110 and enters the protective cover 120 and is respectively assembled with the first gear 461, the overload cylinder 470 and the friction plate 480. The first gear 461 and the friction plate 480 are fixedly mounted on the second shaft body 520, and the overload cylinder 470 is mounted on the second shaft body 520 so as to be rotatable in a circular manner but not axially movable. A notch 471 is provided on the overload cylinder 470, and an overload plate 521 is installed at the corresponding position of the second shaft body 520 and the notch 471. The two sides of the overload plate 521 are respectively assembled and fixed with one end of an overload spring 650, and the other end of the overload spring 650 is assembled and fixed with the inner wall of the notch 471. In the initial state, the overload cylinder 470 and the second shaft body 520 can be relatively fixed in the circumferential direction through two overload springs 650, so that the overload cylinder 470 can rotate synchronously with the second shaft body 520. When the overload cylinder 470 is affected by external force and its rotation, the overload plate 521 will squeeze the overload spring 650 on one side, so that the second shaft body 520 can rotate at a certain angle.

[0054] The friction disc 480 is pressed and contacted with the end surface of the friction plate 640, so that the friction disc 480 and the friction plate 640 are relatively fixed (circumferential direction) by friction force. The friction plate 640 is mounted on the guide shaft 660 and slidably assembled therewith. One end of the guide shaft 660 is fixed on the friction push plate 631, and the other end passes through the friction plate 640 and is assembled and fixed with a nut to prevent the friction plate 640 from falling off the guide shaft 660. The guide shaft 660 is mounted with a friction compression spring 670 on the portion between the friction plate 640 and the friction push plate 631. The friction compression spring 670 is used to generate an elastic force to push the friction plate 640 toward the friction wheel. The friction plate 640 and the friction disc 480 are pressed tightly, so that the second shaft body 520 is relatively fixed in the circumferential direction.

[0055] The friction push plate 631 is fixed on the threaded slider 630, and the threaded slider 630 is sleeved on the fourth shaft body 540 and assembled with it through threaded engagement. The fourth shaft body 540 is respectively assembled with the electrical shell 110 and the side plate 620 for circular rotation, and the second gear 462 is sleeved and fixed on the fourth shaft body 540, and the second gear 462 is meshed with the first gear for transmission. One end of the fourth shaft body 540 passes through the side plate 620 and is assembled and fixed with the second pulley 421. This second pulley 421 is sleeved with another second pulley 21 through the second belt 420 to form a belt transmission mechanism. The other second pulley 421 is sleeved and fixed on the curtain output shaft 711. One end of the curtain output shaft 711 is installed in the curtain motor 710 and the curtain motor 710 can drive the curtain output shaft 711 to rotate forward or reverse in the circumferential direction.

[0056] The threaded slider 630 is engaged and slidably installed in the guide groove 611, and the guide groove 611 is set in the guide shell 610. The guide shell 610 is fixed on the electrical shell 110 and a guide bottom plate 612 is fixed to the bottom surface of the guide groove 611. The guide bottom plate 612 is provided with a guide slide 6122 and a sensing mounting block 6121. The guide slide 6122 and the trigger plate 632 can be slidably assembled. The trigger plate 632 is fixed on the threaded slider 630. The sensing mounting block 6121, the side plate 620 and the trigger plate are respectively installed with a first travel switch 731 and a second travel switch 732 at their corresponding positions. The trigger plate can trigger the first travel switch 731 and the second travel switch 732 respectively, and the first travel switch 731 and the second travel switch 732 will input a signal to the controller of the self-service machine 100 after being triggered, so as to judge that the first belt has moved to the maximum position. At this time, the curtain motor 710 is stopped and the curtain motor is ready to reverse. In this embodiment, the controller is an electrical device installed in the self-service machine for sending and receiving parsed control instructions and performing parameter calculations, and is generally a PLC, CPU, MCU, industrial computer, etc.

[0057] When in use, the infrared temperature measuring module 200 is used to detect the forehead temperature of the user. If the forehead temperature is normal, only the second ultraviolet lamp panel 162 is activated, so that the ultraviolet light is partially blocked by the rolled-up curtain 310 to prevent a large amount of ultraviolet light from leaking out. However, the ultraviolet light irradiates the touch screen at this time, so as to achieve sterilization. At this time, the threaded slider is located at the side farthest from the friction disk.

[0058] Once the forehead temperature is too high, it is considered as a fever. At this time, the controller issues an early warning through a pre-set program, and the user is forced to stop using the self-service machine after the use is completed. Then the blind motor is started, and the blind motor drives the blind output shaft to rotate forward, thereby driving the fourth shaft 540 and the second shaft 520 to rotate in a circle. The fourth shaft drives the threaded slider axially toward the friction disk through the thread, and the second shaft 520 drives the first belt to run after the rotation. The first belt carries the blind 310 to move, so that the blind 310 is unwound from the third shaft, and the blind gradually moves to the bottom of the operating slot until the second travel switch is triggered and the blind motor stops running. At this time, the blind 310 completely blocks the touch screen, and then the first ultraviolet light board and the second ultraviolet light board are started, so that the touch screen is fully irradiated for full sterilization. Preferably, the end face of the blind facing the touch screen is a mirror, which can reflect ultraviolet light, so that the ultraviolet light can fully and highly irradiate the touch screen, so as to greatly increase the sterilization effect. During this process, the friction plate gradually compresses the friction disc, and finally compresses the friction compression spring, thereby compressing the friction plate and the friction disc through elastic force, until the second travel switch is triggered, the friction plate and the friction disc are compressed to relatively fix the second shaft in the circumferential direction. The second shaft will not run in the reverse direction under the elastic force of the spring.

[0059] After the disinfection is completed, when the blind needs to be reset, the blind motor reverses, thereby driving the fourth shaft body and the second shaft body to reverse. At this time, since the friction plate and the friction disc are in a compressed state, the second shaft body will drive the overload plate to compress the overload spring on one side, thereby obtaining a certain angle of rotation. In this process, the fourth shaft body moves the threaded slider away from the friction disc through the thread, so that the friction disc is separated from the friction plate, and then continues to drive the fourth shaft body and the second shaft body to rotate. At this time, the second shaft body and the friction disc rotate synchronously, and the friction disc will be reset by the elastic force of the friction compression spring until the first stroke switch is triggered. After the first stroke switch is triggered, the blind motor stops running, and the blind and the threaded slider are reset. In this process, the blind is rewound on the third shaft body 530 by the elastic force of the spring spring. Through the design of the spring spring, the blind is always taut, so that its mirror surface can also play a reflective effect in the retracted state, so that during ordinary disinfection (only the second ultraviolet lamp board is started), it can not only block part of the ultraviolet light, but also reflect the ultraviolet light, thereby increasing the disinfection effect.

[0060] In this embodiment, the existing self-service machine shell is enlarged during the prototype manufacturing so as to accommodate the infrared temperature measurement module and the blind mechanism, thus not affecting the internal layout and function of the self-service machine. Of course, the infrared temperature measurement module and the blind mechanism can be placed externally respectively, so as not to affect the structure of the self-service machine. However, in this case, a top plate 101 where the plug-in motor is located needs to be added to the self-service machine (in the figure, it is integrated with the electrical shell, but it can be detached). Since most self-service machines do not have this top plate, it is not difficult to add it.

[0061] The matters not described in detail in the present invention are all known technologies to those skilled in the art.

[0062] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
