Technical Field

[0001] The utility model belongs to the technical field of Internet of Things security, and in particular relates to an Internet of Things security switch. Background Art

[0002] In today's era of rapid technological development, household appliances and electronic devices are becoming increasingly popular, bringing great convenience to people's lives. However, these devices also bring certain safety hazards, especially for children. Children are curious and lack self-protection awareness, so accidents such as electric shock and burns are prone to occur when using household appliances. Therefore, developing a safety switch that can effectively prevent children from using it is of great significance to ensure children's safety.

[0003] In the prior art, although there are some safety measures for children, such as sockets with locks, child locks, etc., these measures often have certain limitations. First, the popularity of these safety measures is not high, and they are not widely adopted in many families and public places. Secondly, existing safety measures often require the active participation of adults, such as manually opening or closing the lock, which increases the difficulty of use to a certain extent and is prone to safety hazards due to adult negligence. In addition, the design of some safety measures is not user-friendly, the operation is complicated, and it is not easy to understand and use, which also limits their actual application effect. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned defects and propose an Internet of Things safety switch, which aims to improve the safety of children using electrical appliances through intelligent and automated design.

[0026] The following is a further detailed description of the embodiments of the invention in conjunction with the accompanying drawings to make the objectives, technical solutions and technical effects of the invention more clearly presented.

[0027] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional 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 limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0028] like Figure 1-2 As shown, the utility model discloses an Internet of Things safety switch, comprising a body 1, an infrared detection module 2, an infrared distance measurement module 3, a limit module 4, a monitoring module 5, and a control module 6 arranged in the body 1. Specifically:

[0029] The infrared detection module 2 is installed in the body 1 and faces the switch button 7, and is used to detect whether an object approaches the switch button 7. The infrared detection module 2 uses an infrared proximity sensor, such as a PIR sensor, to detect whether a user approaches the switch button 7. The infrared detection module 2 is set on the switch button 7.

[0030] Two infrared distance measuring modules 3 are provided and are respectively located on the left and right sides of the body 1, for detecting the distance of the object relative to the body 1. The infrared distance measuring module 3 is an infrared distance measuring sensor, which detects the distance of the object relative to the switch body 1.

[0031] The limit module 4 is arranged in the body 1 and close to the switch button 7, and is used to limit the opening of the switch button 7. The limit module 4 can be a mechanical limit device or an electronic limit switch, and is used to limit the opening of the switch button 7. When the switch button 7 is closed, the limit hole on the switch button 7 is coaxially aligned with the slider.

[0032] The monitoring module 5 is connected to the infrared ranging module 3 and is used to monitor and receive the ranging signal sent by the infrared ranging module 3. The monitoring module 5 can be a microcontroller or a single chip microcomputer, which receives the ranging signal sent by the infrared ranging module 3 and processes it.

[0033] The control module 6 is respectively connected to the infrared detection module 2, the infrared ranging module 3, the monitoring module 5 and the limit module 4, and controls the opening / closing of the limit module 4 according to the signal sent by the monitoring module 5 to limit the switch button 7. The control module 6 is a microcontroller or a single-chip microcomputer, which is integrated with an input / output control interface, connected to the infrared detection module 2, the infrared ranging module 3, and the monitoring module 5, and controls the opening and closing of the limit module 4 according to the input signal.

[0034] By integrating multiple modules, this technical solution can automatically detect the approach of an object and perform corresponding operations according to the distance between the object and the switch. When an object approaches the switch button 7, the infrared detection module 2 will detect this action and trigger the infrared distance measurement module 3 to measure the distance. According to the measurement results, the monitoring module 5 will determine whether the preset threshold is reached, and then the control module 6 will decide whether to open or close the limit module 4, thereby controlling the opening of the switch button 7. In addition, through the connection between the Bluetooth module and the smart terminal, the user can remotely control the switch to achieve a smarter interactive experience.

[0035] The above scheme further provides a limit structure for cooperating with the implementation of the above scheme. Specifically, the limit module 4 includes a sleeve fixed in the body 1, a slider arranged in the sleeve, and an electromagnet corresponding to the slider, the slider can slide out or slide in relative to the sleeve, and the electromagnet is arranged at both ends of the sleeve to form an electromagnetic force to control the sliding of the slider; the switch button 7 is provided with a limit hole corresponding to the sliding of the slider.

[0036] In order to adapt to different needs, especially the body width and height of ordinary users, the infrared distance measurement module 3 is hinged on the left and right sides of the body 1 through an adjustable swivel block, and the adjustable swivel block rotates left and right relative to the body 1.

[0037] The above solution further includes a Bluetooth module, and the Bluetooth module is used to connect to the smart terminal.

[0038] It should be clear that there is a significant difference between the body size of children and adults, which can also be clearly reflected when using the switch. For example, adults are large in size and stand at a certain distance when turning on the switch, while children are the opposite and will move closer to the switch. In this way, the two infrared ranging modules 3 can measure the distance to the obstacles on the left and right respectively. In fact, for adults, no matter which side of the switch they stand on, the distance should be greater than the set threshold; while for children, it is just the opposite. Based on the above situation, the utility model realizes a safe switch for children.

[0039] The utility model system utilizes infrared detection module 2 and infrared ranging module 3 to detect the user's approach and distance. Infrared detection module 2 is installed on the switch button 7, and can sense the user's approaching touch, while infrared ranging module 3 is installed on both sides of the body 1. Through the cooperation of the two sensors, the relative distance between the user and the switch can be measured. Specifically, the measuring distance of a sensor should be within a set range, that is, the normal standing distance of an adult. The limit module 4 controls the sliding of the slider through the electromagnetic force generated by the electromagnet, thereby limiting the opening of the switch button 7. The monitoring module 5 receives the ranging signal and calculates it, and the control module 6 controls the opening or closing of the limit module 4 by combining the calculation results and the infrared detection signal.

[0040] Specific steps:

[0041] First, the infrared detection module 2 detects whether a person is approaching the switch button 7. Once a person is detected approaching, the infrared ranging module 3 starts working to measure the distance between the person and the switch. Subsequently, the monitoring module 5 receives the ranging signal and analyzes and determines whether the preset threshold is reached. If the threshold is reached, the control module 6 sends a signal to the limit module 4, and the electromagnet generates an electromagnetic force to control the slider to slide, thereby turning on or off the switch button 7. At the same time, the user can also connect to the smart terminal through the Bluetooth module to realize the operation of the remote control switch. The whole process is automated. The user only needs to approach the switch or send instructions through the smart terminal, and the system can automatically complete the corresponding operation.

[0042] The above description is only a preferred feasible embodiment of the present invention and is not intended to limit the scope of the patent application of the present invention. All equivalent changes, equivalent substitutions or modified changes performed within the technical spirit and principles suggested by the present invention should be included in the scope of patent protection covered by the present invention.
